Abstract

The authors demonstrate vertical cavity lasers utilizing tapered apertures to close the active region, permitting good current confinement combined with low optical scattering losses. Because the slope efficiency remains high at small sizes, devices >=2micro m in diam. have wall-plug efficiencies of > 20%. By better scaling, wall-plug efficiencies of 17-25% are achieved at low output powers of 100-500micro m. [on SciFinder (R)]
