In a paper published in Nature Photonics, U of T Engineering researchers report a new solar cell that may pave the way to inexpensive coatings that efficiently convert the sun's rays to electricity. The U of T researchers, led by Professor Ted Sargent, report the first efficient tandem solar cell based on colloidal quantum dots (CQD). "The U of T device is a stack of two light-absorbing layers "“ one tuned to capture the sun's visible rays, the other engineered to harvest the half of...

A new generation of high speed, silicon-based information technology has been brought a step closer by researchers in the Department of Electronic and Electrical Engineering at UCL and the London Centre for Nanotechnology. The team's research, published in next week's Nature Photonics journal, provides the first demonstration of an electrically driven, quantum dot laser grown directly on a silicon substrate (Si) with a wavelength (1300-nm) suitable for use in telecommunications. Silicon is...

Two researchers working for Wellman Center for Photomedicine at Massachusetts General Hospital have developed a laser from a single living cell, by engineering it to produce a light-emitting protein that was first obtained from glowing jellyfish. The development, set to appear in the journal Nature Photonics, was worked on by researchers Malte Gather, PhD, and Seok Hyun Yun, PhD. They described that flooding the genetically engineered cells with weak blue light caused them to emit directed,...

Researchers report in Nature Photonics that they have set a new record of 26 terabits of data per second for the rate of data transfer using a single laser. The entire Library of Congress collections could be sent down an optical fiber in just 10 seconds at this new record rate. The researchers used a "fast Fourier transform" to unpick over 300 separate colors of light in a laser beam, each encoded with its own string of information. "With 26 terabits per second, you can simultaneously...

By Diana Lutz, Washington University in St. Louis An ultrasound guide star and time-reversal mirror can focus light deep under the skin, a game-changing improvement in biomedical imaging technology Astronomers have a neat trick they sometimes use to compensate for the turbulence of the atmosphere that blurs images made by ground-based telescopes. They create an artificial star called a guide star and use its twinkling to compensate for the atmospheric turbulence. Lihong Wang, PhD, the Gene...

Engineers at the University of California, Berkeley, have found a way to grow nanolasers directly onto a silicon surface, an achievement that could lead to a new class of faster, more efficient microprocessors, as well as to powerful biochemical sensors that use optoelectronic chips. They describe their work in a paper published Feb. 6 in an advanced online issue of the journal Nature Photonics. "Our results impact a broad spectrum of scientific fields, including materials science, transistor...

Combined optic and electronic technology holds promise for new nanoscale sensing devices, Pitt and University of Wisconsin-Madison team reports in Nature Photonics University of Pittsburgh researchers have created a nanoscale light sensor that can be combined with near-atomic-size electronic circuitry to produce hybrid optic and electronic devices with new functionality. The team, which also involved researchers from the University of Wisconsin at Madison, reports in Nature Photonics that the...

Researchers pace embryonic heart with laser Love, exercise and, new research shows, an infrared laser can make a heart beat faster. Scientists at Case Western Reserve University and Vanderbilt University found that pulsed light can pace contractions in an avian embryonic heart, with no apparent damage to the tissue. The work, "Optical pacing of the embryonic heart," will be published in the advanced online issue of Nature Photonics on Aug. 15, 2010. According to the scientists, this...

TAU scientists explore a new method for curving "Airy" light beams We learned in science class that light beams travel in straight lines and spread through a process known as diffraction "” and they can't go around corners. But now researchers at Tel Aviv University are investigating new applications for their recent discovery that small beams of light can indeed be bent in a laboratory setting, diffracting much less than a "regular" beam. These rays, called "Airy beams," were named...

A new technique for revealing images of hidden objects may one day allow pilots to peer through fog and doctors to see more precisely into the human body without surgery. Developed by Princeton engineers, the method relies on the surprising ability to clarify an image using rays of light that would typically make the image unrecognizable, such as those scattered by clouds, human tissue or murky water. In their experiments, the researchers restored an obscured image into a clear pattern of...

Nature Photonics is a peer-reviewed scientific journal established in 2007 and published monthly by the Nature Publishing Group. As with other Nature journals, this periodical has no external Editorial Board with editorial decisions made by a fully-functioning in-house team. The journal covers research related to optoelectronics, laser science, imaging, communications, and other aspects of photonics. It publishes review articles, research papers, news and commentary, and research...
