Abstract
An optoelectronic apparatus includes a semiconductor substrate, an electrically activated spatial light modulator disposed on the semiconductor substrate, and a vertical-cavity surface-emitting laser (VCSEL) disposed over the spatial light modulator on the semiconductor substrate. A controller is coupled to actuate the VCSEL to emit a beam of optical radiation and to control the spatial light modulator so as to modify an optical property of the beam.
