Abstract:
An integrated photonic beam steering device includes a planar photonic substrate. An input waveguide is configured to accept an electromagnetic energy from a source of electromagnetic energy radiation. A first splitter is configured to split the electromagnetic radiation into one or more paths. One or more phased array rows are optically coupled to each of the one or more paths. Each phased array row includes a row splitter configured to split the each of the one or more paths into two or more row paths. Two or more phase modulators are each optically coupled respectively to each of the two or more row paths. Two or more output couplers are optically coupled respectively to each phase modulator output of the two or more phase modulators. The two or more output couplers are configured to radiate a steered photonic beam away from the integrated photonic beam steering device.
