For the first time, a group of chemists, physicists, and engineers has developed crystalline materials that allow an optical fiber to have integrated, high-speed electronic functions. The potential applications of such optical fibers include improved telecommunications and other hybrid optical and electronic technologies, improved laser technology, and more-accurate remote-sensing devices.
The research was initiated by Rongrui He, a postdoctoral researcher in the Department of Chemistry at Penn State University. The international team, led by John Badding, a professor of chemistry at Penn State, will publish its findings in the journal Nature Photonics.
Badding explained that one of the greatest current technological challenges is exchanging information between optics and electronics rapidly and efficiently. Existing technology has resulted in sometimes-clumsy ways of merging optical fibers with electronic chips -- silicon-based integrated circuits that serve as the building blocks for most semiconductor electronic devices such as solar cells, light-emitting diodes (LEDs), computers, and cell phones.
"The optical fiber is usually a passive medium that simply transports light, while the chip is the piece that performs the electrical part of the equation," Badding said. "For example, light is transmitted from London to New York via fiber-optic cables when two people set up a video call on their computers. But the computer screens and associated electronic devices have to take that light and convert it to an image, which is an electrical process. Light and electricity are working in concert in a process called an OEO conversion, or an optical-electrical-optical conversion."
The integration of optical fibers and chips is difficult for many reasons. First, fibers are round and cylindrical, while chips are flat, so simply shaping the connection between the two is a challenge. Another challenge is the alignment of pieces that are so small. "An optical fiber is 10 times smaller than the width of a human hair. On top of that, there are light-guiding pathways that are built onto chips that are even smaller than the fibers by as much as 100 times," Badding said. "So imagine just trying to line those two devices up. That feat is a big challenge for today's technology."
To address these challenges, the team members took a different approach. Rather than merge a flat chip with a round optical fiber, they found a way to build a new kind of optical fiber with its own integrated electronic component, thereby bypassing the need to integrate fiber-optics onto a chip.
To do this, they used high-pressure chemistry techniques to deposit semiconducting materials directly, layer by layer, into tiny holes in optical fibers. "The big breakthrough here is that we don't need the whole chip as part of the finished product. We have managed to build the junction -- the active boundary where all the electronic action takes place -- right into the fiber," said Pier J. A. Sazio of the University of Southampton in the United Kingdom and one of the team's leaders.
Sazio added that one of the key goals of research in this field is to create a fast, all-fiber network. "If the signal never leaves the fiber, then it is a faster, cheaper, and more efficient technology," said Sazio. "Moving technology off the chip and directly onto the fiber, which is the more-natural place for light, opens up the potential for embedded semiconductors to carry optoelectronic applications to the next level. At present, you still have electrical switching at both ends of the optical fiber. If we can actually generate signals inside a fiber, a whole range of optoelectronic applications becomes possible."

ST Micro to improve smartphone cameras with 40W LED flash
STMicroelectronics hopes to make blurry low-light images from smartphone cameras a thing of the past with a new chip designed to boost light output from LED-based flashes.
The ideal camera flash delivers a lot of light in a short time, freezing action and illuminating more distant objects. Professional cameras use a xenon strobe light to produce a brief burst - or flash - of light, but the lighting on smartphone cameras is typically provided by an LED.
The light output of a battery-powered LED is continuous, and much lower in intensity than a flash, leading to longer exposure times and darker, blurrier pictures.
But ST hopes to change that with its new STCF04 multifunction chip, which it says can control flash power up to 40W, compared to perhaps 2W for typical LED flashes today.
The key is the chip's ability to control the charging and discharging of a supercapacitor, which it uses to gradually store energy from the phone's battery and then deliver it to the LED in a short burst. That's similar to the way that xenon strobes work, but the LED-supercap combination does the job with just a few volts, making it much safer - and the components more compact -than the hundreds or thousands of volts needed to drive a xenon strobe.
ST's chip, just 3 millimeters square, will add US$2 or less to the cost of a cell phone, it said.
It contains a charger to store energy in a supercap, and a driver for an external transistor used to deliver 40 watts or more of peak power from the supercapacitor to a bank of LEDs. It also contains a temperature sensor to detect when the LEDs are in danger of overheating - useful if they are being used as a torch rather than a flash; a light sensor for setting the exposure and flash intensity, and a driver for an auxiliary LED used either as a privacy indicator (you're on camera) or perhaps to help autofocus systems in low light.
The chip's built-in timer can be used to set the flash duration in steps of around one-100,000th of a second, although it takes around one-3,000th of a second for the LED to reach full power, according to ST. The controller can also discharge the supercap in stages to produce several flash pulses in a row, useful for red-eye reduction.

New LED stoplights to save Huntington $200K
Huntington motorists will soon see a decrease in the amount of time they spend sitting at traffic lights.
The City of Huntington began installing the light system in Fall 2011. David Hagley, public works directors, said the new light system would be installed at 55 intersections by the end of 2012.
The light system has been commonly referred to as a "smart system." There are no bulbs — the traffic lights and displays are all energy efficient LED lighting.
"All new lights will be LED, all communication will be controlled wirelessly from the Rahall Transportation Institute," Hagley said.
The new system will alleviate problems experienced with the old traffic system. Each new light will communicate wirelessly. In the past, wires have not adapted to years of wear and tear.
"Over time, wires were severed and broke down," Hagley said. "The old lights had sensor wires in the pavement that were easily torn up."
Aside from communicating wirelessly, the new light system would have a camera system that will sense traffic patterns. Hagley said the system will make for a safer commute, drivers will be less aggravated, as sitting at a pointless red light will be a thing of the past.
"It should alleviate frustrations," Hagley said. "There are camera sensors that will get people moving through red lights. There will be less idle time ‘cause the lights are going to work as a system instead of individually."
Hagley said aside from cutting down road rage, less idle time in traffic means the new system will cut down harmful emissions.
Kim Wolfe, Huntington mayor said the new lights are going to save the city quite a bit of money.
"There will be approximately a $200,000 savings in energy costs, ‘cause these are the modern LED lighting," Wolfe said. "Fewer repairs on the smart system would also save the city in labor costs."
Wolfe said the new system is being funded by an air quality grant. The wireless communication allows the city to direct traffic flow for disasters or special events from one location.
The lights have been installed at major intersections downtown. Hagley said the system will improve the overall commuting experience for Huntington.
"It's going to make things better," Wolfe said. "I'm glad to see the improvement coming."

Choose carefully
Well, that's not quite the only difference between the old bulbs and their replacements, notes Steve Walker, manager of the Batteries Plus store in Elgin. The store's owner decided a few weeks ago that this would be an opportune time to start selling a large selection of light bulbs in addition to its line of batteries.
Yes, the new styles will use less electricity and save big on your ComEd bill, Walker notes. But they also will cost more up front. They don't all provide the same kind of warm-feeling, all-around colors we have gotten used to. And some types have enough mercury to require them to be recycled as semi-hazardous waste rather than just being tossed into the trash.
Halogen incandescent bulbs, which also use a material that glows hot and bright when an electric current passes through it but use a different kind of material than the tungsten filaments typically used in old-style bulbs. These use less power than the old bulbs but more than the other alternatives. For example, one halogen bulb offered for sale at Batteries Plus gives the same amount of light as an old-style 75-watter but draws only 53 watts.
Compact fluorescent lights, or CFLs, which are similar to the long tubes used for decades in office and store lighting and use hot gases to generate their light. The compact ones typically have a small tube wrapped into a spiral shape. If you think that's ugly, or you have a lampshade designed to snap onto the old-style incandescent, CFLs now also come in a rounded shape that looks much like the old-style bulbs on the outside.
CFLs use less power than halogen incandescents. The one equivalent to an old-style 75 uses just 20 watts, in effect cutting your electric bill for using it by three-fourths. CFLs are the type that contain a small amount of mercury, an environmental hazard, but hardware stores and Batteries Plus will accept them for recycling.
LED (light-emitting diode) bulbs, which are the most high tech bulbs of all. They are similar to the LEDs used in electronic dials and some brake lights, flashlights and traffic signals.
They're the most efficient type of all from the standpoint of power use, but also are the least well developed at this point. Remember how dim those LED Christmas decorations seem to be? LEDs strain to achieve the same kind of brightness as a living-room lamp, and in fact the brightest LED available at Batteries Plus puts out only one-third as much light as a 75-watt incandescent bulb.
But the new styles may last so long that over the life of a lamp, the purchase price looks more reasonable. According to the website of Phillips Electronics, if an old-style bulb burns out in a given usage in one year, a halogen bulb in the same usage will last two years, a CFL will last seven to 11 years, and an LED bulb will burn on and on and on for at least 15 years.
Walker said some users have complained that CFLs burn out sooner than that, but he thinks that depends on how the bulb is being used.
"You need the right bulb for the right application," Walker said. "If someone has a closet light that they switch on and off all the time for just a few seconds at a time, that will be hard on a CFL. But for a porch light that turns on once a day and stays on for hours, a CFL will last a long, long time."
Add in the savings on your electric bill, and ComEd and the Alliance to Save Energy argue that using the newfangled, expensive-to-buy bulbs usually ends up saving money over the long run.
Also, ComEd will help you some with the purchase cost. Just a few years ago, the utility would provide its customers with free replacement bulbs that they could pick up at grocery stores such as Gromer's in return for paying just a few dollars a year more on their power bills.

No room at the inn as Bethlehem celebrates Christmas
In Rome, thousands of the faithful gathered in the Vatican's St Peter's Square as night fell for the blessing of a giant Nativity scene to the sound of accordions, hurdy gurdies and Christmas carols.
Pope Benedict XVI appeared at his window shortly after 1700 GMT to light an oil lamp for peace and make the sign of the cross as a blessing to the crowd in the square below.
Peace was also a central theme in Patriarch of Jerusalem Fuad Twal's Christmas homily to be delivered in Bethlehem.
"We ask for peace, stability and security for the entire Middle East," the homily reads. Twal, the most senior Roman Catholic in the Middle East, urges "the return of calm and reconciliation in Syria, in Egypt, in Iraq and in North Africa" in the text of a speech published ahead of delivery at midnight mass in the place of Christ's birth.
In popular uprisings in Tunis and Egypt which ended decades of "secular" dictatorships, Islamist parties have taken the front stage. Egypt's main
Islamist parties emerged on Saturday as winning 65 per cent of votes for party lists in the second round of the new parliament.
The UN Security Council says that Syria has killed more than 5,000 of its people in recent months, and Thursday attacks in Iraq killed 60 people, heightening sectarian tensions less than a week after US troops withdrew.
"O Child of Bethlehem, in this New Year, we place in your hands this troubled Middle East and, above all, our youth full of legitimate aspirations, who are frustrated by the economic and political situation, and in search of a better future," Twal's homily reads.
It also addresses the Palestinians, welcoming Palestinian Authority president Mahmud Abbas who was to attend the mass, and congratulating him "in his unfaltering efforts to achieve a just peace in the Middle East, a main thrust of which is the creation of a Palestinian State."
The address says the Palestinians "recently turned to the United Nations in the hope of finding a just solution to the conflict," and notes that "they have been asked to re-engage in a failed peace process," which "has left a bitter taste of broken promises and of mistrust."
As day broke on the not-so-little-town of Bethlehem, a few miles south of Jerusalem, residents readied to welcome thousands of pilgrims who wanted to see where the Bible says Jesus was born to a couple from Nazareth.
In the afternoon, Twal made his solemn entry into the birthplace of Christ accompanied by Palestinian Scouts playing bagpipes, an inheritance from the British mandate in the first half of the 20th century.
The procession led to Manger Square in central Bethlehem, where a huge poster at Omar's Mosque showed Abbas and late Palestinian leader Yasser Arafat.
Hotels and guest houses across this ancient town perched on the hilltops were packed to capacity, Palestinian officials said, with more than 50,000 visitors from around the world expected.
"Hotels are full. We have no rooms left even though the number of hotel rooms has multiplied in the last three years," Palestinian tourism minister Khulud Daibes told AFP.
