Past laureates within this field have included the inventor of the Integrated Circuit (Jack St. Clair Kilby); the team that developed the worlds first microprocessor (Federico Faggin, Marcian Hoff, Stanley Mazor and Masatoshi Shima); researchers who created the first room-temperature semiconductor laser (Zhores Alferov, Izuo Hayashi and Morton Panish); and the inventor of the liquid-crystal display (George Heilmeier). The 2009 Kyoto Prize in the Basic Sciences category will be awarded... (Yahoo! Wire -- Entertainment News)
Laser With Controlled Polarization: Innovation Opens Door To Wide Range Of Applications In Photonics And Communications Apr 20, 2009
"The novelty of our approach is that instead of being conducted externally, which requires bulky and expensive optical components, manipulation of the beam polarization is achieved by directly integrating the polarizer on the laser facet. This compact solution is applicable to semiconductor lasers and other solid-state lasers, all the way from communication wavelengths to the mid-infrared and Terahertz spectrum" ... (July 28, 2008) Scientists have demonstrated, for the first time, highly... (Science Daily)
