High-efficiency 660-nm VCSEL exhibiting 26.47% peak wall-plug efficiency and improved high-temperature performance up to 65°C.
We demonstrate a high-performance 660-nm vertical-cavity surface-emitting laser (VCSEL) employing a strain-compensated GaInP/AlGaInP active region and an asymmetric AlGaAs distributed Bragg reflector (DBR). By engineering a -10 nm room-temperature spectral detuning (λgain - λcavity), we compensate for the differential...
