Infrared Spectrometer Filter Is Electrically Tunable
Mar 1, 2002 — Portable infrared spectrometers enable in situ analysis of compounds in a variety of hazardous environments on Earth and in space. Such possibilities have led researchers at Ryukoku University in Otsu, Japan, to develop a small, robust infrared filter that can be tuned electrostatically to select specific wavelengths. Most spectrometers use a Michelson interferometer with a moving mirror, a fixed mirror, a beamsplitter and a light source, but their design is bulky and overly sensitive to...
Dressing Particles Takes Time
Mar 1, 2002 — Physicists have typically assumed that a free charged particle introduced into a nonequilibrium Coulomb system instantaneously becomes a "dressed" particle, completely integrated into the system. However, researchers from Technische Universität...
0.1-Hz Detector Could Measure Cosmic Acceleration
Mar 1, 2002 — We are on the cusp of the gravity-wave revolution in astronomy. Numerous detectors -- powered by bars of metal or by beams of light, on the ground or in orbit -- are scheduled to come online over the next 10 years or are awaiting approval to do so,...
Bright White Organic LED Developed

Silicon on Sapphire Speeds Chip Communication
Mar 1, 2002 — The insulating properties of sapphire have been heralded as a boon to smaller, low-power chip design, but researchers at Johns Hopkins University in Baltimore are focusing on the gem's optical potential for laser chip communication at speeds a...
Near-Field Microscopy Catches Smallest Laser in Action
Mar 1, 2002 — Using a near-field scanning optical microscope, researchers at the University of California in Berkeley have captured images of tiny nanowire lasers in action. Led by Richard Saykally, they have applied a combination of femtosecond spectroscopy and...
'Slow Light' May Enable Benchtop Black Holes
Mar 1, 2002 — Ulf Leonhardt of St. Andrews University in St. Andrews, UK, hopes to bring black holes -- or, at least, an optical analog of their event horizons -- to the lab. In the Jan. 24 issue of Nature, he describes how the manipulation of an...
Coupled-Resonator VCSEL Produces High Output
