Abstract

Experimental results for a monolithic singlemode vertical-cavity surface-emitting laser (VCSEL) at 1.55 µm are reported. Single-transverse-mode operation with >40 dB sidemode suppression and a peak power of 1.03 mW at 20°C is obtained. Far-field measurements show low divergence with a measured far-field angle of 7.9° at 1 mW output power.
