Abstract
An optical phased array, includes, in part, K beam processors each adapted to receive a different one of K optical signals and generate N optical signals in response. The difference between the phases of optical signals aand ais the same for all Ms, where M is an integer ranging from 1 to N−1 defining the signals generated by a beam processor, and L is an integer ranging from 1 to K defining the beam processor generating the K optical signals. The transmitter further includes, in part, a combiner adapted to receive the N×K optical signals from the K beam processors and combine the K optical signals from different ones of the K beam processors to generate N optical signals. The transmitter further includes, in part, N radiating elements each adapted to transmit one of the N optical signals.
