Abstract:
1. An ultra-fast, compact optical phased array apparatus for optical beam steering, comprising: a first substrate comprising a top surface and a bottom surface; an array of air core photonic crystal waveguides in the first substrate comprising an input on the top surface of the first substrate and an output on the bottom surface of the first substrate; columnar members etched in a hexagonal close pack around each air core photonic crystal waveguide; a pair of metal electrodes around the hexagonal close pack columnar members of each air core photonic crystal waveguide; a trench around the pair of metal electrodes of each air core photonic crystal waveguide; a second substrate coupled to the top surface of the first substrate comprising electrical interconnection lines and vias coupled to each pair of metal electrodes; and a substrate guided wave holographic fanout array comprising:
