Research & Technology News
Photorefractive Volume Gratings Stabilize Wavelengths
May 1, 1998 — A research team from the National Research Laboratory of Metrology in Tsukuba, Japan, has stabilized the wavelengths of two diode lasers by using two photorefractive volume gratings in one lithium niobate (LiNbO3) crystal. Both wavelengths exhibited good short- and long-term stability, and the photorefractive crystal allowed effective control of the separation of the wavelengths. Diode lasers with stable wavelengths are a must for applications in high-resolution spectroscopy. There are several...
Physicist Pushes Multilayer CDs
May 1, 1998 — A Russian-born physicist, who emigrated from the Soviet Union more than two decades ago, has persuaded the Russian parliament to invest in a company that would manufacture multilayer fluorescent discs. Eugene Levich heads two firms that have shares...
Probing the 'Glory Ring' Mystery
May 1, 1998 — Ever notice bright, colored rings around a distant airplane? Researchers have described this phenomenon as a strong backscattering of light by droplets of water. While the theory was well-developed, it remained difficult to verify experimentally....
Researchers Find Privacy in Chaos
May 1, 1998 — Communication can be chaotic enough when the communicators stand face to face. Introducing technology into the equation can sometimes aggravate potential misunderstandings. Who, then, would want to throw even more chaos into the communication...
Spatial Light Modulator Yields Full-Color Images
May 1, 1998 — A standard silicon wafer is the key to a technology that could make possible miniature, low-power, color displays, such as those used in portable or headmounted devices. Developed by researchers at the University of Edinburgh in the UK, the...
Stained-Glass Physics Help Detect HIV
May 1, 1998 — Sheldon Schultz, a scientist at the University of California at San Diego, has used "plasmon resonant particles" to detect HIV antibodies in blood samples. When particles resonate in this way, they absorb the wavelengths that set off the...
Airborne Laser Passes First Test
Apr 1, 1998 — Aircraft manufacturer Boeing Co. of Seattle has concluded the first series of wind tunnel tests on components crucial to the Airborne Laser. The weapon system is designed to destroy theater ballistic missiles in the initial phase of...
Apache Point's Telescope Nears Completion
Apr 1, 1998 — The final pieces of the Apache Point Observatory's new telescope have arrived, marking the beginning of a multiyear project to produce a three-dimensional picture of the universe. The delivery included the optics of one spectrograph and an...
Blue Lasers Aim at Optical Data Storage, Display Markets
Apr 1, 1998 — In the latest entry in the race to develop a high-power blue laser, SDL Inc. has introduced a semiconductor laser based on gallium nitride. The San Jose, Calif.-based company's entry emits at multiple wavelengths between 400 and 410 nm and features...
Chinese Scientists Seek Release of Jailed Physicist
Apr 1, 1998 — After a Taiwan-born physicist recently pleaded guilty to passing classified information on nuclear weapons to China, a group of Chinese scientists launched an appeal to the US for his release. Scientists from the government-run Chinese Academy of...
Component Manufacturer Puts the Bend in Optical Fiber
Apr 1, 1998 — As the photonics industry marches toward miniaturization, one component manufacturer plans to improve telecommunications technology with a way to create 180° optical fiber bends with low losses and small diameters. Thomas & Betts Corp. of...
Custom X-Ray Lenses Aid Astrophysical Imaging
Apr 1, 1998 — The National Research Council's Solid State Electronics Institute is producing custom optics for scientists who want to develop their own x-ray optical systems for astrophysical investigation or synchrotron radiation research. Researchers rely...
Diode-Pumped Kilowatt Laser Is Brighter, More Powerful
Apr 1, 1998 — With the goal of advancing diode-pumped solid-state laser technology by making lasers brighter and more powerful, TRW Inc. of Redondo Beach, Calif., introduced its newest diode array-pumped kilowatt laser at Photonics West. The company says this...
Medical Imaging Analysis Technology Used in Radar Applications
Apr 1, 1998 — Researchers from the National Imagery and Mapping Agency in Chantilly, Va., and BioComputer Research Inc. in Trion, Ga., have investigated an application for algorithms developed for medical sonogram image analysis. The algorithms had been used to...
Micromirrors Perform Telecom Task
Apr 1, 1998 — SScientists at Bell Labs, the R&D segment of Lucent Technologies in Murray Hill, N.J., have demonstrated a device that incorporates free-space optics and micromirrors to route and switch individual wavelengths transmitted simultaneously over...
Microscope Looks into Centrifuge
Apr 1, 1998 — Researchers at the Marine Biological Laboratory have designed a microscope that allows scientists to see the alignment of molecules in a sample as it spins at high speed in a centrifuge. With this device, scientists will be able to see the changes...
New CCD Could Improve Telescope Resolution
Apr 1, 1998 — With few exceptions, charge-coupled devices have become the preferred method for imaging the universe. There has been one problem: Atmospheric changes such as high winds cause images to blur. To create clearer, more visible images, John Tonry and...
New Fiber Offers Higher Speeds
Apr 1, 1998 — In an effort to meet the increasing demands of high-bandwidth communications networks, Corning Incorporated of Corning, N.Y., introduced its newest single-mode optical fiber at the Optical Fiber Communications Conference in February. Dubbed LEAF,...
Optical Imaging of Cardiac Condition Aids Physicians
Apr 1, 1998 — Medical researchers from the University of Alberta in Edmonton, Canada, may be a step closer to understanding the causes of a severe cardiac condition known as ventricular fibrillation through a series of high-resolution movies that show how the...
Optical Lithography Creates Subangstrom Features in Silicon
Apr 1, 1998 — A group of researchers at the University of Texas has shown the world that conventional optical lithography can continue to produce ever smaller features on computer microchips without resorting to next-generation plasma laser, ion or electron...
Optics Give Hard Drives a New Lease on Life
Apr 1, 1998 — The Winchester-style disk drive, nearing the limits for magnetic storage, has been given a new lease on life, thanks to optics. Computer hard-drive maker Seagate Technology and its Quinta Corp. subsidiary have combined optical switching, fiber...
Photonics Reaps What Farm Denizens Sow
Apr 1, 1998 — Lasers in factories, fiber bundles in operating rooms, even cameras sitting on computer monitors are common sights. Now, based on work being done at the University of North Carolina, optical systems could be found next to every silo or manure pile....
Probes May Aid Retinal Surgery
Apr 1, 1998 — Industrial research projects aimed at manufacturing tiny optical probes may have repercussions in the tricky world of ophthalmic surgery. Peter Bryanston-Cross, a professor and researcher with the Optical Engineering Laboratory at the University of...
Quantum Cascade Laser Lights a Fire at Photonics West
Apr 1, 1998 — Lighting a match with a laser doesn't seem like that big a deal, unless it's done at room temperature using far-IR light from a diode laser. It was in such a fashion that the inventor of quantum cascade laser diode architecture, Federico Capasso of...
Quantum Mechanical Transistor Promises Photonic Applications
Apr 1, 1998 — Scientists at Sandia National Laboratories in Albuquerque, N.M., have developed a quantum mechanical transistor that may increase the accuracy of optical detectors and energy spectrometers. The transistor takes advantage of a phenomenon described in...
