Abstract
The fabrication and performance characteristics of a vertical cavity surface emitting laser design which uses lateral current injection for low resistance and lateral oxidation for carrier confinement is described. The 4 μm diameter devices have a threshold current of ~1.5 mA and emit few mW. The 50 μm diameter devices have a threshold current of ~200 mA and emit ~250 mW in a single wavelength. The lasers emit at near 1 μm
