Spectrometer Measures Salt in Salmon Caviar
Feb 1, 2001 — For years, the preparation of ikura -- also known as salmon caviar -- was something of an art form. Producers soaked the harvested eggs in a brine solution that extended the final product's shelf life and, if done correctly, preserved taste and texture. But preparation of ikura has undergone a sea change as modern diets have begun demanding lower salt content. Coincident with this demand, markets for the roe have expanded eastward across the Atlantic, which have brought about more stringent...
New Method Improves Optical Fiber Attachment to Substrates
Feb 1, 2001 — The Holy Grail for telecommunications companies today is something called the all-optical network. Constructed entirely of fiber optic pathways -- from long distance underground cables, to local area networks, metropolitan networks, and building...
Study Says Midsized Businesses Looking for Broadband Connectivity in Key Locations, DSL a Likely Suspect for Service
Feb 1, 2001 — SCOTTSDALE, Ariz., Feb. 1 -- US midsized companies (100-999 employees) are expected to show growing demand for DSL services in the year 2001, according to Cahners In-Stat Group.
Staff Report
Feb 1, 2001 — Cameras, lasers and instrumentation help law-enforcement officers track down evidence and people in criminal investigations. Patrick Baxter, serving time in New York for car theft, was indicted last November on charges in three murder cases, one of...
Clever Cameras Do More Than See
Feb 1, 2001 — A picture may be worth a thousand words, but sometimes what’s needed are just a few: good, bad, accept, reject. In manufacturing, product assessment is often based on visual data. A human then processes that data many times to form a quality...
Fast Coatings for DWDM Filters
Feb 1, 2001 — Current and forecast market requirements for dense wavelength division multiplexing (DWDM) filters are driving the need for ever-increasing production throughput. Manufacturers are calling for larger substrate diameters, enhanced uniformity and...
Have You Hugged Your Fiber Today?
Feb 1, 2001 — The information explosion ignited by the Internet has created an insatiable appetite for bandwidth. To appease the bandwidth hunger, most telecommunications operators are pushed to increase the per-channel data rate of wavelength division...
Ball vs. Gradient Index Lenses
Feb 1, 2001 — In modern communications systems, micro-optic components couple light between fibers, from laser diodes to fibers and from fibers to detectors. They also collimate light from fibers i thin-film multiplexing. Both ball lenses and gradient index of...
The Big Trade-Off
Feb 1, 2001 — Semiconductor lasers are very small (about the size of a grain of salt), very efficient electrically powered sources of coherent light. In the mid-1980s, their availability in large quantities and with long lifetimes enabled several applications,...
Untangling the Wavelength Web
Feb 1, 2001 — The growth of the Internet is fundamentally reshaping communications and proving that too much bandwidth is not enough. According to communications research firm RHK Inc. of South San Francisco, the explosive growth of Internet Protocol traffic...
San Jose Offers Laser ’Boot Camp’
