A method for fabricating crystalline dielectric material on top of metal layers to produce an apparatus for non-mechanical steering of an input laser beam is provided. The apparatus may include a plurality of stacked parallel dielectric waveguides, each waveguide of which is fabricated by separating layers of dielectric material from a donor wafer and bonding the separated layers of dielectric material to a receiving wafer. A plurality of voltages is applied across the stacked parallel dielectric waveguides. Each of the stacked parallel dielectric waveguides is electrically phase modulated to deflect an output beam in a predictable manner.

A laser-based infrared countermeasure (IRCM) system is disclosed. The IRCM system includes a set of receive optics, a dichroic filter, first and second detectors, a lens module and a laser. Receive optics are configured to receive optical information. The lens module reflects the optical information from the receive optics to the dichroic filter. The dichroic filter selectively splits the optical information to the first and second detectors. The first and second detectors, each of which is formed by a single-pixel detector, detects a potential missile threat from the optical information. Based on information collected by the first and second detectors, the laser sends laser beams to neutralize any missile threat.
