Laser Spot Aims at Storage Market
MURRAY HILL, N.J. -- MURRAY HILL, N.J. -- A relatively simple solution to the problem of reducing a laser’s spot size using near-field optics may lead to an optical storage system that could store as much as 500 Gb/in.2 of data, up to 100 times current storage densities. Researchers at Lucent Technologies’ Bell Laboratories are working with Siros Technologies Inc. of San Jose, Calif., to commercialize the very-small-aperture laser, which has built-in near-field optics. Typically, laser spot size is...

How Photons Work
Aug 1, 2000 — The study of light has been inextricably linked to the advancement of scientific thought for more than 2000 years. From Euclid to Newton to Einstein, many of the great treatises of science have been directed toward unraveling light’s...
For Pixels, Size Matters
Aug 1, 2000 — In the rat race for ever-higher pixel counts for the digital still camera market, it is clear that, if the chip size must remain constant, then "more pixels" inherently means "smaller pixels." The driving force to keep the silicon area of the sensor...
Photonics Rules of Thumb
Aug 1, 2000 — Scientists and engineers tend to want to answer simple relational questions with a blackboard covered with equations, even when questioners just want a rough estimate to gauge whether a change would cause more problems than it would fix. The "rules...
Squelch the Noise
Aug 1, 2000 — The silicon positive-intrinsic-negative (PIN) photodiode is a ubiquitous component that detects light in photometric devices from fluorescence instruments in the laboratory to laser speed guns on the highway. Each application has different...
High-Tech ’Vision’ Test
