Abstract
An array of devices for electronically steering a laser beam. A plurality of quantum well absorption modulators steer a laser beam, either reflective or transmissive, without moving parts and operable at room temperature. The foregoing is accomplished using intraband, also termed intersubband, transitions in the quantum wells.
