Abstract
An apparatus includes a photonic integrated circuit having multiple cells. Each cell includes first and second antenna elements, where the first antenna element is configured to receive a portion of optical energy and the second antenna element is configured to transmit the portion of the optical energy. Each cell also includes a signal pathway configured to transport the portion of the optical energy between the first and second antenna elements. Each cell further includes a phase modulator configured to adjust a phase of the portion of the optical energy transported over the signal pathway. The apparatus also includes multiple wavefront sensors configured to measure wavefront errors in the portions of the optical energy. The apparatus further includes multiple phase controllers configured to adjust operation of the phase modulators in order to at least partially reduce the wavefront errors.
