Abstract
A beam-steering engine, comprising an optical element switchable between a first operational mode and a second operational mode, in the first operational mode of the optical element the beam-steering engine is configured to output an input light beam incident on the beam-steering engine along a first propagation direction and in the second operational mode of the optical element the beam-steering engine is configured to output the input light beam incident on the beam-steering engine along a second propagation direction. A transition of the optical element between the first and second operational modes is characterized by a transition time period that varies with a temperature of the optical element. The beam-steering engine further includes a device to control a temperature of the solid-state optical element to maintain the transition time period below a certain limit.
