1.3 and 1.5 μm wavelength wafer fused InAlGaAs/InP-AlGaAs/GaAs VCSELs with high single mode output power

The performance of 1.3 and 1.5 μm emission wavelength VCSELs fabricated by double wafer fusion for communication and chemical sensing applications is reported in this paper. Light-current and voltage-current characteristics of the devices are measured at different heat sink temperatures. Results show high laser performance with record high single mode output power.
