Cavity length dependence of photopumped lasing properties of MOCVD-grown ZnSe/ZnMgSSe double-heterostructure

摘要

An internal loss of 4.6 cm/sup -1/ is estimated from the cavity length dependence of photopumped blue lasing at room temperature (RT) with a ZnSe/ZnMgSSe double-heterostructure (DH) grown by metal organic chemical vapour deposition (MOCVD). The low internal loss being comparable to that of molecular beam epitaxy (MBE)-grown DH, implies the feasibility of realising an MOCVD-grown DH device.
