Study on intra-cavity contacted oxide-confined vertical cavity surface emitting laser

An intra-cavity contacted oxide-confined InGaAs/GaAs VCSEL had been fabricated by low-pressure metal organic chemical-vapor deposition (LP-MOCVD) and a three axes self-aligning process technique. The optical standing wave field of the VCSEL was simulated. In addition, the temperature performance of the VCSEL has also been investigated by using the SV-32 cryostat and LD2002C5 test system. A CW light output power of 8 mW was obtained at 35 mA. The small change of threshold current across a broad range of temperature from 243-333.1 K suggests an excellent temperature performance.
