Abstract
An apparatus includes a photonic integrated circuit having an optical phased array, where the optical phased array includes multiple unit cells. Each unit cell includes (i) an antenna element configured to transmit or receive optical signals and (ii) a phase modulator configured to modify phases of the optical signals being transmitted or received by the antenna element. The apparatus also includes a gyroscopic sensor configured to sense movement of the photonic integrated circuit, where at least a portion of the gyroscopic sensor is integrated within the photonic integrated circuit.
