Summary: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) at least one antenna element configured to transmit or receive optical signals and (ii) a modulator configured to phase-shift the optical signals transmitted or received by the antenna element. Each unit cell is configured to transmit or receive light having multiple polarizations in the optical signals.
