P-N Junction Diode Ultra-Violet Lasers with Directional Emission from Non-Circular Optical Cavities for Bio Sensing

摘要

The objectives of the past 12 months has been directed toward greater understanding of the laser emission from the spiral structure and achieving for the first time, electrically pumped spiral micro-lasers. Another objective was to develop micro-amplifiers which could increase the output emission. During the October 2002 site visit of Lt. Col. John Carrano of DARPA and program manager of the SUVOS program, it became apparent that the low scale collaboration between Yale and PARC was so successful and providing exciting possibilities, that Lt. Col. Carrano stepped up the funding for PARC to increase their collaboration efforts with Yale. Therefore, besides just providing samples for us in our optical pumping approach, as was the case in the past, PARC began to actively investigate the electrical pumping approach with close collaboration with the Yale group.
