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) 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.

An apparatus comprising:
- a photonic integrated circuit comprising an optical phased array, the optical phased array comprising multiple unit cells, each unit cell comprising (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 at least one antenna element;
- wherein the at least one antenna element of each unit cell is configured to simultaneously transmit or simultaneously receive light having multiple polarizations in the optical signals.
A method comprising:
- using an optical phased array of a photonic integrated circuit to transmit or receive optical signals, the optical phased array comprising multiple unit cells, each unit cell comprising (i) at least one antenna element configured to transmit or receive the optical signals and (ii) a modulator configured to phase-shift the optical signals transmitted or received by the at least one antenna element;
- wherein the at least one antenna element of each unit cell simultaneously transmits or simultaneously receives light having multiple polarizations in the optical signals.
