| 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. |
