Daewon, Corning Sign Fiber Supply Agreement
Oct 2, 2001 — CORNING, NY, Oct. 2 -- Corning Incorporated and Daewon Cable of Korea have signed a long-term supply contract for Corning SMF-28 single-mode fiber. Corning will provide approximately 90 percent of Daewon Cable's total single-mode fiber requirements through 2005. Daewon is a significant supplier to the Korean telecommunications market, as well as other select global markets. Daewon was recently contracted to supply high-performance optical fiber cable to a Korea Telecom project, valued at US $8...
Lucent Signs TyCom for New Undersea Fibers
Oct 2, 2001 — AMSTERDAM, The Netherlands, Oct. 2 -- Lucent Technologies said that TyCom Ltd. will be its first customer for UltraWave optical fibers; a new family of fibers created by Lucent's Optical Fiber Solutions (OFS) business that enables submarine network...
A Basement Full of Lasers
Oct 1, 2001 — It's a short walk from the third floor of the Welch Building on the University of Texas campus to the basement of the Engineering Science Building. That's enough, however, for mid-August in Austin to work its magic. Temperatures above 100 make the...
Technology Close-Up
Oct 1, 2001 — How much valuable time have machine vision developers spent sifting through vast arrays of expensive and often incompatible connectors and cables from camera manufacturers and frame grabber suppliers? Too much -- which is why many developers...
Photonics Design and Solutions
Oct 1, 2001 — Consistency and repeatability are difficult tasks in diode laser manufacturing, but they are critical for high-volume manufacturing of devices that users can trust to work as promised. Process repeatability, still the nemesis of most semiconductor...
Sensitive Detection
Oct 1, 2001 — Capillary electrophoresis is a modern analytical separation technique that has steadily gained importance in recent years, especially in bioanalytical, clinical and pharmaceutical applications. Electroseparation in fused-silica capillaries is...
Giving a Green Light
Oct 1, 2001 — Green lasers have been important since the very first days of the laser. Indeed, many of the earliest applications in medicine, graphics and basic research demonstrated the versatility of green laser light, particularly from the argon-ion...
Intensified Fluorescence
Oct 1, 2001 — Fluorescence is a central technology in medical testing, drug discovery, biotechnology and imaging. In almost all uses of fluorescence, the fluorophores are in the free-space condition, in which they radiate energy with minimal interactions with...
Future Computing
Oct 1, 2001 — Seventeen years ago, Alan Huang wrote in the Proceedings of the IEEE about the prospects of optical computing. The barriers were, he said, not so much technological, "but more and more [challenges] of imagination." Today many of the promises he...
Veeco Acquires Applied Epi
Oct 1, 2001 — Veeco Instruments has agreed to acquire Applied Epi, a St. Paul, Minn., manufacturer of molecular beam epitaxy equipment used in making high-speed III-V compound semiconductor devices for photonic and electronic devices. The acquisition will cost...
Navy OKs Multispectral Imager Contract
LAKEHURST, N.J. -- The Naval Air Warfare Center has awarded Optics 1 Inc. a five-year, $25 million contract to develop an advanced multispectral optical surveillance system. The system will add short-wave infrared (1 to 2.5 µm) and advanced sensors to a...
NASA Contractor Pleads Guilty in Laser Fraud
ORLANDO, Fla. -- An excimer laser developer has pleaded guilty to four charges that accuse him of accepting payments for lasers that he did not deliver and accepting services for which he did not pay. In an Aug. 3 plea agreement, Philip D. Bolen of Altamonte...
Industrial Laser Shipments Down
Oct 1, 2001 — Laser manufacturers shipped 13 percent fewer industrial lasers and systems in the second quarter of 2001 than in the same period in 2000, according to the Association for Manufacturing Technology's Laser Systems Product Group. Shipments by the 47...
US Debates Export Regulation Changes
Oct 1, 2001 — The US Senate voted last month to rewrite export control laws related to military/commercial dual-use technology, possibly making it easier for photonics companies to sell "mass market" products abroad. The 1979 Export Administration Act...
Calculate Value in Manufacturing Flexibility
UNIVERSITY PARK, Pa. -- Buying a new production tool seems like a straightforward decision, but new research suggests that conservative estimates may not give enough weight to the value of flexibility in manufacturing. Many photonics companies manufacture (and sell)...
China Alters Patent Laws
Oct 1, 2001 — As one step toward entry into the World Trade Organization, China has changed some of its patent laws to bring it closer to compliance with the Agreement on Trade-Related Aspects of Intellectual Property Rights (the TRIPS Agreement). New...
Bellows Improves Laser Resonator Seals
Oct 1, 2001 — The stability and reliability of the argon-ion laser has made it a workhorse for a range of applications from writing masks for semiconductor circuits to measuring the flow rate of cell protoplasm. As countless subtle improvements continue to...
Chip Rotation Doesn't Disorient Vision System
Oct 1, 2001 — Imaging integrated circuits is a simple enough task for today's machine vision technology, but problems emerge when a vision system also must identify microscopic details on slightly skewed dies at near-blinding speeds. It is not uncommon for...
16 Megapixels Drive Camera Back
Oct 1, 2001 — Traditional full-frame image sensors did not offer Phase One's professional camera customers the photoresponse that they required for their work. The traditional CCD's polysilicon gate structure absorbs too many of the incoming photons, which makes...
In Situ Spectrometers Deliver Fast Solution
Oct 1, 2001 — Most pharmaceutical laboratories operate on limited time. Once patented, a new drug substance must navigate development and clinical trials before its manufacturer can see a return on its investment. The more sales made during the remaining life of...
Ordinary CCDs Survive Radiation Environments
Oct 1, 2001 — Charged with the responsibility of cleaning up one of the country's most dangerous toxic waste dumps, CH2M Hill Hanford Group began looking for inexpensive video camera systems that could resist flammable gas and radioactive environments. The...
Quantum-Dot Lasers Produce >5 mW
Oct 1, 2001 — Researchers at Universitat Wurzburg in Germany have demonstrated InAs/GaInAs quantum-dot lasers that produce more than 5 mW of 1.3-µm light at room temperature. The lasers, which exhibited threshold currents of 6 mA, display continuous-wave...
Laser Deposits ITO on Flexible Substrate
Oct 1, 2001 — A team of researchers at the Naval Research Laboratory in Washington has grown thin films of indium tin oxide on flexible substrates of polyethylene terephthalate using pulsed laser deposition. The technique may enable the production of organic LED...
Motorola Grows GaAs on Silicon
TEMPE, Ariz. -- While III-V semiconductors have revolutionized electronics and photonics, the expense of their manufacture has limited widespread application. Researchers at Motorola Labs promise this will change. They have learned how to grow gallium arsenide on...
Single-Photon Detector Flashes Faster
ROCHESTER, N.Y. -- Photodetectors typically require high gain to respond to the energy of a single photon, but gain mechanisms take time to reset between photon events and thus limit the detector bandwidth to approximately 10 MHz. High gain also makes single-photon...
