Short wavelength optoelectronics: Status and challenges
University of Bremen, Otto-Hahn-Allee, Bremen 28359, Germany
Optoelectronic in the blue-UV region based on AlGaN/GaN/InGaN structures is developing rapidly and first DVD players with a 410nm laser diode (LD) inside (Blue Ray Disc, 23 GB) made by Sony are now available in Japan. Nevertheless big problems remain to be solved for nitride laser diodes. One is to go to shorter wavelength than 360nm the other to cover wavelength longer than 480nm. Till now electrically pumped lasing of nitride structures was only possible within this spectral range.
