Abstract

Electronically steerable laser sources have applications in areas such as optical display, free space communications, and illumination. Among the multiple figures of merit for beam steering, speed is still a limiting factor for many applications including laser radar [1]. While mechanical methods clearly have inertial limitations, even the fastest available liquid crystal optical phased array techniques are limited to speeds under 10 kHz [2, 3]. We show that electronic beam steering using phased vertical cavity surface emitting laser (VCSEL) arrays [4-6] can be steered as fast as 100 MHz while possessing the inherent advantages of system robustness, radiation hardness, and energy efficiency.
