Lasing at 1.460 μm from a monolithic, GaInNAsSb vertical cavity surface emitting laser (VCSEL), the longest wavelength on GaAs to date, is demonstrated. Threshold current was 0.58 A (17 kA/cm2), pulsed with a duty cycle of 0.1%. The VCSEL was cooled to reach threshold, from 700 mA at 0°C to 580 mA at -10°C.
