Alfalight, Inc., a leading supplier of highly efficient high-power diode lasers, announced today the first details of its breakthrough Surface-Emitting Distributed Feedback (SE-DFB) laser diode technology. This technology uses a significantly different approach at the wafer level to provide a lower-cost system solution with enhanced brightness and ruggedness compared to the edge-emitting laser technology.
A research associate at the U.S. Air Force Academy's Laser and Optics Research Center here is developing a new capability that will allow satellites to be seen and see clearer.
The Canadians are gathering at Photonics West 2009 in San Jose, CA with OCRI representatives to build on what a new industry report says is a shining success. In its survey entitled "Illuminating a World of Opportunity," the Canadian Photonics Consortium states Canada has 370 photonics companies employing some 20,000 people who collectively generate close to $4.5 billion annually, with approximately 85% from exports including 50% to the U.S.
Bookham, Inc. (Nasdaq: BKHM), a provider of optical components for industrial applications, has achieved an output power of 200W with a 10mm laser diode bar - believed to be the industry's most powerful commercially available continuous wave (CW) single bar product.
An optimized TO38 package makes the blue laser diode from OSRAM Opto Semiconductors the smallest in its class, bringing the world one step closer to a vision of tiny projectors that can be integrated into mobile devices such as cell phones and digital cameras.
JDSU (NASDAQ: JDSU and TSX: JDU) today announced at the SPIE Photonics West availability of a new ultraviolet (UV) filter, an optical component critical to instrument makers and used for applications such as environmental monitoring, genetic research, biomedical instrumentation, and medical/aesthetic laser instrumentation.
Innolume, the leading provider of Quantum Dot (QD) laser diodes and modules covering the 1064nm to 1320nm optical spectrum, today announced that it will be presenting a technical paper on its revolutionary comb-laser at Photonics West in San Jose, California January 27th (Paper 7230-21, Session 5: Integration and Devices for Comms, 10:30 AM).
The principle behind whispering galleries - where words spoken softly beneath a domed ceiling or in a vault can be clearly heard on the opposite side of the chamber - has been used to achieve what could prove to be a significant breakthrough in the miniaturization of lasers. Ultrasmall lasers, i.e., nanoscale, promise a wide variety of intriguing applications, including superfast communications and data handling (photonics), and optical microchips for instant and detailed chemical analyses.
A team of physicists and engineers has demonstrated an optical device that filters two particles of light (or photons) based on the correlations between their polarisation that are only allowed in the seemingly bizarre quantum world. This so called "entanglement filter" passes the pair of photons only if they inhabit the same quantum state, without the user (or anything else) ever knowing what that state is.
Tiny disk-shaped lasers as small as a speck of dust could one day beam information through optical computers. Unfortunately, a perfect disk will spray light out, not as a beam, but in all directions. New theoretical results, reported in the Optical Society (OSA) journal Optics Letters, explain how adding a small notch to the disk edge provides a single outlet for laser light to stream out.
