The room-temperature continuous-wave (CW) electrical operation of antimonide-based long wavelength vertical-cavity surface-emitting lasers (VCSEL) on GaAs, with record powers and high temperature operation was presented. Singlemode powers of 0.3 mW at 10° C and 0.1 mW at 70° C and sidemode suppression ratios up to 42 dB were also achieved. It was observed that the optical powers were approaching the OC-48 short reach (SR) specifications, indicating the suitability of such VCSEL for communication applications.
