Abstract

A phase-controlled optical waveguide antenna array including an optical splitter, an array of phase shifters, and an optical waveguide antenna array is disclosed. The optical splitter divides the input light to a plural of optical waveguides, the phase shifter is connected to an optical waveguide of the optical splitter, and the optical waveguide antenna array is connected with the phase shifters. The optical waveguide antenna array employs periodic block structure to output a uniform light beam, and the phase shifters are tuned with adjacent thermal heaters to steer the output beam angle of the optical waveguide antenna array.
