We report over 130°C continuous wave operation of unbonded vertical cavity top-surface emitting lasers emitting more than 1.0 mW at 110°C. Furthermore, we control threshold currents to within only ±1.35 mA (±12%) over a 150°C temperature range. We are also able to control the threshold current to within a factor of 2 over a 50 nm wavelength range using the same epidesign.
