Abstract
In this paper, we present monolithic 910 nm high-power vertical-cavity surface-emitting laser (VCSEL) arrays with addressable sectors suitable for long-distance light detection and ranging (LIDAR). The peak output power of a single VCSEL array (163 devices) reaches 25.5 W under 30-ns-pulse operation. The peak power of the larger sectored 2×2 VCSEL array reaches 100 W at an operating current of 55 A. To the best of our knowledge, this is the first report on achieving a 100 W output power level with a 910 nm VCSEL array at such a low driving current. Our VCSEL array shows stable impulse response characteristics and uniform far-field spot morphology.
