英文摘要	we present a study on the facet damage profile of quantum cascade lasers (qcls). conspicuous cascade half-loop damage strips on front facet are observed when qcls catastrophically failed. due to the large difference on thermal conductivities between active region and the substrate, dominant heat is compulsively driven to the substrate. abundant heat accumulation and dissipation on substrate build large temperature gradient and thermal lattice mismatch. thermal-induced stress due to sequential mismatch leads to the occurrence of the multistep damages on front facet. good agreement is achieved between the observed locations of damaged strips and the calculated results.; submitted by 阎军 (yanj@red.semi.ac.cn) on 2010-04-28t01:21:39z no. of bitstreams: 1 thermal induced facet destructive feature of quantum cascade lasers.pdf: 351971 bytes, checksum: 10a53ffbfdeeeb3226557d8d37fbdd0c (md5); approved for entry into archive by 阎军(yanj@red.semi.ac.cn) on 2010-04-28t01:22:04z (gmt) no. of bitstreams: 1 thermal induced facet destructive feature of quantum cascade lasers.pdf: 351971 bytes, checksum: 10a53ffbfdeeeb3226557d8d37fbdd0c (md5); made available in dspace on 2010-04-28t01:22:04z (gmt). no. of bitstreams: 1 thermal induced facet destructive feature of quantum cascade lasers.pdf: 351971 bytes, checksum: 10a53ffbfdeeeb3226557d8d37fbdd0c (md5) previous issue date: 2010; national research projects of china 60525406 60736031 60806018 60906026 2006cb604903 2007aa03z446 2009aa03z403; 其它
