Abstract
Abstract
Неre we report a monolitic long-wavelength vertical cavity surface-emitting laser based on GaAs with bottom GaAs/AlGaAs distributed Bragg reflectors (DBRs), metamorphic optical cavity with In0.41Ga0.59As/In0.25Ga0.75As-active region providing emission near 1.3 μm with high modal optical gain and top dielectric SiO2/Ta2O5 DBRs. We achieve continious wave single-mode operation at room temperature under optical pumping. The proposed approach has potential for high output power and high temperature (up to 200 °C) stable operation.
