Feds Crack Down on Laser Pointers
Feb 16, 2006 — ROMULUS, Mich., Feb. 16, 2006 – After 16 pilots complained that someone shined potentially blinding laser light into their cockpits while they were landing at Detroit Metropolitan Airport on Monday night, federal authorities say they are cracking down on what they consider to be a growing threat to airplane safety. According to published reports, it was the second rash of incidents at the airport in the past six months. The FAA has said that there were 305 laser incidents between late 2004 and...
GA Tech Researchers Create a More Compact, Less Costly Spectrometer
Feb 8, 2006 — ATLANTA, Feb. 8, 2006 -- Researchers at the Georgia Institute of Technology have developed a way to make spectrometers -- optical instruments used as the main parts of sensors to detect substances present in even ultrasmall concentrations -- more...
World's Smallest Silicon Modulator Created
Feb 1, 2006 — AUSTIN, Texas, Feb. 1, 2006 -- An electrical engineer at The University of Texas at Austin has made a laser light blink while it passes through a miniaturized silicon chip, a major step toward developing commercially viable optical interconnects for...

News Briefs
Dec 30, 2005 — Semiconductor developer TechnoConcepts Inc. of Van Nuys, Calif., announced that its subsidiary, Techno (Hong Kong) Ltd. has opened its new headquarters at the Hong Kong Science & Technology Park (HKSTP). Techno provides the company with...
Study Moves 'Superlens' Closer to Reality
Dec 26, 2005 — CORVALLIS, Ore., Dec. 26 -- Physicists at Oregon State University say they have made an important advance toward the creation of a functional "superlens" -- an optical device that bends light differently than any natural material -- which could be...
PHOTOMETRY STANDARD
Dec 1, 2005 — The ISO 23539:2005(E)/CIE S 010/E:2004 standard: Photometry — The CIE System of Physical Photometry has been released by the International Standardization Organisation and the Commission Internationale de L’Éclairage. The system specifies procedures...
Gratings Couple Optical Fibers to Silicon Photonic Devices
Nov 1, 2005 — Advances in silicon photonics have ignited an intense interest in optical devices based on silicon (see pages 53, 62 and 68). An inherent problem with the application of this technology, however, is the low efficiency with which light can be coupled...
LASERS SIMPLIFIED
Sep 1, 2005 — Intended for nonscience majors who are taking courses in general science, physics, optics, technology or electrical engineering, the book Is There a Laser in the House? Understanding Your High-Tech Everyday World uses common devices and natural...
Condensates Coaxed to Exhibit Unique Interference
May 1, 2005 — Thomas Young's classic setup for the demonstration of interference features light from one source incident on two vertical slits because the phenomenon occurs only if the light from the slits has a well-defined relative phase. Now a group at the...
NONIMAGING OPTICS
Apr 1, 2005 — Nonimaging Optics explores a growing field that is applicable to areas where the collection, concentration, transport and distribution of light is important. Applications include testing, measurement, signal detection, illumination optics and solar...
Controlling Spontaneous Emission with Photonic Crystals
Mar 1, 2005 — Nearly two decades ago, photonic bandgap crystals were proposed as the ultimate means for controlling the propagation and emission of light.1,2 Since that time, research into photonic crystals has exploded, with much attention devoted to controlling...
Light Moves Water Droplets
Sep 1, 2004 — A team at Arizona State University in Tempe reported in the Aug. 26 issue of Journal of Physical Chemistry B that a nanostructured surface morphology similar to that of lotus leaves imparts the ability to move 15-µl droplets of water using light....
OSA Recognizes Achievements
Sep 1, 2004 — Based in Washington, the Optical Society of America has bestowed its annual distinction awards upon 20 individuals for their commitment, initiative and creativity in the optics field. The prizes will be presented during the society's annual meeting...
Optical Fractionation Presented
Apr 1, 2003 — Researchers from the University of Chicago presented their findings on the use of light to continuously sort microscopic particles at the March meeting of the American Physical Society in Austin, Texas. The technique, which they call optical...
Ruby Crystal Slows Light at Room Temperature
Apr 1, 2003 — Over the past few years, researchers such as Lene Vestergaard Hau of Harvard University in Cambridge, Mass., have reported fantastic experiments in which they slow light to a crawl --and even stop it temporarily -- in ultracold clouds of atoms. Now...
Scrambling to Reduce Polarization-Related Impairments
Apr 1, 2003 — Polarization is a fundamental property of light. In classical physics, light is modeled as a sinusoidal electromagnetic wave in which an oscillating electric field and an oscillating magnetic field propagate through space. Polarization is defined in...
