摘要

Abstract: We report batch-processed, totally planar, vertical-cavity top surface emitting GaAs/AlGaAs laser devices and arrays. Different size devices are studied experimentally. We measure continuous- wave threshold currents down to 1.7 mA and output powers $GRT 3.7 mW at room temperature. We also discuss interesting characteristics such as differential quantum efficiencies exceeding unity and multi-transverse mode behavior. An array having 64 $MUL 1 individually-accessed elements is characterized and shown to have uniform room-temperature continuous-wave operating characteristics in threshold current $APEQ 2.1 $POM 0.1 mA, wavelength $APEQ 849.4 $POM 0.8 nm, and output power $APEQ 0.5 $POM 0.1 mW.!13
