Abstract
A device includes a photonic integrated circuit having an optical phased array. The optical phased array includes multiple array elements, where each array element includes (i) an antenna element configured to transmit or receive optical signals and (ii) a phase modulator configured to phase-shift the optical signals transmitted or received by the antenna element. The device also includes multiple digital register in integrated circuit (DRIIC) cells, where each DRIIC cell is associated with one of the array elements. The DRIIC cells are configured to receive digital inputs and to provide outputs to the phase modulators of the associated array elements in order to control the phase-shifts of the optical signals transmitted or received by the antenna elements based on the digital inputs.
