Abstract
An electro-optical includes, in part, a multitude of phase modulators each of which includes, in part, a p-type semiconductor region, an n-type semiconductor region, and a χ(2) insulating dielectric material disposed between the p-type and n-type semiconductor regions. The electro-optical device may be a phased array in which each phase modulator is associated with a different one of the transmitting elements of the phased array. The χ(2) insulating dielectric material may be an organic polymer. The electro-optical device may further include, in part, a multitude of sensors each associated with a different one of the phase modulators. Each sensor is adapted to receive a phase modulated signal generated by the sensor's associated phase modulator. The electro-optical device may further include, in part, a multitude of amplitude modulators each associated with a different one of the multitude of phase modulators.
