Abstract :
High performance 1.3 μm vertical-cavity surface-emitting lasers (VCSELs) using oxygen implantation in wafer-bonded GaAs-AlGaAs mirrors are demonstrated. A record low threshold current density of 454 A/cm2 and a threshold current of 0.83 mA have been achieved for pulsed operation at 20°C. The maximum CW and pulsed operating temperatures are 40 and 112°C, respectively
