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 an antenna element configured to transmit or receive optical signals having a linear polarization of light. Each unit cell also includes a modulator configured to phase-shift the optical signals transmitted or received by the antenna element. Each unit cell further includes a quarter waveplate configured to convert between the linear polarization of light and a circular polarization of light.
