Conservation of quantum efficiency in quantum well intermixing by stress engineering with dielectric bilayers
Arslan, Seval; Demir, Abdullah; Şahin, Seval; Aydınlı, Atilla (IOP Publishing LTD, 2018)In semiconductor lasers, quantum well intermixing (QWI) with high selectivity using dielectrics often results in lower quantum efficiency. In this paper, we report on an investigation regarding the effect of thermally ... -
IFVD-based large intermixing selectivity window process for high power laser diodes
Arslan, Seval; Şahin, Seval; Demir, Abdullah; Aydınlı, Atilla (Spie-Int Soc Optical Engineering, 2018)Catastrophic optical mirror damage (COMD) is a key issue in semiconductor lasers and it is initiated by facet heating because of optical absorption. To reduce optical absorption, the most promising method is to form ...
