| 英文摘要 | a 7.8-mu m surface emitting second-order distributed feedback quantum cascade laser (dfb qcl) structure with metallized surface grating is studied. the modal property of this structure is described by utilizing coupled-mode theory where the coupling coefficients are derived from exact floquet-bloch solutions of infinite periodic structure. based on this theory, the influence of waveguide structure and grating topography as well as device length on the laser performance is numerically investigated. the optimized surface emitting second-order dfb qcl structure design exhibits a high surface outcoupling efficiency of 22% and a low threshold gain of 10 cm(-1). using a pi phase-shift in the centre of the grating, a high-quality single-lobe far-field radiation pattern is obtained.; submitted by 阎军 (yanj@red.semi.ac.cn) on 2010-05-24t06:45:23z no. of bitstreams: 1 design of surface emitting distributed feedback quantum cascade laser with single-lobe far-field pattern and high outcoupling efficiency.pdf: 330636 bytes, checksum: fa3852507e51d2a6f10ed82fed92e20d (md5); approved for entry into archive by 阎军(yanj@red.semi.ac.cn) on 2010-05-24t07:17:04z (gmt) no. of bitstreams: 1 design of surface emitting distributed feedback quantum cascade laser with single-lobe far-field pattern and high outcoupling efficiency.pdf: 330636 bytes, checksum: fa3852507e51d2a6f10ed82fed92e20d (md5); made available in dspace on 2010-05-24t07:17:04z (gmt). no. of bitstreams: 1 design of surface emitting distributed feedback quantum cascade laser with single-lobe far-field pattern and high outcoupling efficiency.pdf: 330636 bytes, checksum: fa3852507e51d2a6f10ed82fed92e20d (md5) previous issue date: 2010; national science fund for distinguished young scholars of china 60525406 national natural science foundation of china 60736031 60806018 60906026 national basic research program of china 2006cb604903 national high technology research and development program of china 2007aa03z446 2009aa03z403; 其它 |
