Communication is the key to effectively carrying out optical design projects while shortening design cycles and reducing manufacturing costs because it enables the customer and the designer to work as a team to identify tradeoffs that can be made to save time and money without sacrificing the effectiveness of the design.
Shuji Nakamura's seemingly single-handed invention of practical gallium nitride–based blue and UV lasers and light-emitting diodes (LEDs) during his stint at Nichia (Kaminaka, Japan) has made him one of the few optoelectronics researchers to receive publicity in the general press...
"Immersion" was the word at the SPIE Microlithography 2004 meeting (Santa Clara, CA; Feb. 22–27) as chipmakers put off the tough climb to 157-nm optical lithography and opted instead for the slippery and wet descent to 45-nm and smaller feature sizes based on argon fluoride (ArF) 193-nm lithography technology.
When a planet with an atmosphere passes in front of a star (an event known as an occultation), earthbound scientists can glean information about the planet's atmosphere by examining how the starlight dims and winks out, then reappears.
Biophysicists from Cornell University (Ithaca, NY) have joined forces with a chemist from Université de Rennes (Rennes, France) to tackle one of the biggest optical-imaging challenges in neuroscience: imaging electrical impulses in the brain.
In a development that may one day help in the fabrication of nanometer-scale optical devices, engineers at Nippon Telegraph and Telephone Corp. (NTT: Tokyo, Japan) have created an electron-beam (e-beam) lithographic system that patterns features in three dimensions with minimum feature sizes of 10 nm.
Two groups of researchers have advanced the use of electrowetting droplets for displays, with one demonstrating a new way of exploiting the optical geometry of the liquid used, and another developing video-speed performance and a new strategy for incorporating color.
A fast modulator made of silicon (Si) may make researchers take another look at the material, which has been largely forsaken by the optoelectronics industry in favor of other semiconductors with more favorable light-manipulating properties.
Using technology based on a continuous-wave near-IR imager first demonstrated in 1996 by Britton Chance, emeritus faculty at University of Pennsylvania (Philadelphia, PA), and colleagues, a research team headed by Chance is looking for signs of blood vessels generated by tumors in cancerous breasts.
Active-photonic-lattice distributed-feedback lasers emit a diffraction-limited surface-normal beam. These lasers can be coherently combined into arrays that could potentially emit 50 W of continuous-wave IR light.
