Abstract
A photonic integrated circuit. The photonic integrated circuit includes: a plurality of antenna elements, an element of the plurality of antenna elements having an electrical port and including: a first laser configured to produce laser light of a first wavelength; and a first radiative patch conditionally connected to the electrical port and connected, by an optical connection, to the laser, the first radiative patch including, as a major component, a semiconductor material configured to be conductive when illuminated by light having the first wavelength, and to be nonconductive when not illuminated, the first radiative patch being configured, when conductive, to convert an electric signal received at the electrical port to radiated electromagnetic waves, or to convert received electromagnetic waves to an electrical signal at the electrical port.
