英文摘要	we demonstrate a novel oxide confined gaas-based photonic crystal vertical cavity surface emitting laser (pc-vcsel) operating at a wavelength of 850 nm based on coherent coupling. a ring-shaped light-emitting aperture is added to the conventional pc-vcsel, and coherent coupling is achieved between the central defect aperture and the ring-shaped light-emitting aperture. measurements show that under the continuous-wave (cw) injected current of 20 ma, a high power of 2 mw is obtained, and the side mode suppression ratio (smsr) is larger than 20 db. the average divergence angle is 4.2 degrees at the current level of 20 ma. compared with the results ever reported, the divergence angle is reduced.; submitted by 阎军 (yanj@red.semi.ac.cn) on 2010-04-13t14:00:26z no. of bitstreams: 1 a novel photonic crystal vertical cavity surface emitting laser based on coherent coupling.pdf: 1304744 bytes, checksum: 9f4b79b2f20191638092d5287569c403 (md5); approved for entry into archive by 阎军(yanj@red.semi.ac.cn) on 2010-04-13t14:14:36z (gmt) no. of bitstreams: 1 a novel photonic crystal vertical cavity surface emitting laser based on coherent coupling.pdf: 1304744 bytes, checksum: 9f4b79b2f20191638092d5287569c403 (md5); made available in dspace on 2010-04-13t14:14:36z (gmt). no. of bitstreams: 1 a novel photonic crystal vertical cavity surface emitting laser based on coherent coupling.pdf: 1304744 bytes, checksum: 9f4b79b2f20191638092d5287569c403 (md5) previous issue date: 2010; national natural science foundation of china 10634080 60677046；national basic research program of china 2006cb921700；national high technology research and development program of china 2006aa03z403; 其它
