Abstract

See full text

Phase-change metasurface waveguide mode converters and photonic computing systems including a phase-change metasurface waveguide mode converter are described. In an embodiment, the phase-change metasurface waveguide mode converter include a plurality of phase-change antennas comprising a phase-change material and protruding from a surface, wherein each phase-change antenna of the plurality of phase-change antennas is configured to scatter an optical waveguide mode and cause a phase shift of light travelling through an optical waveguide optically coupled thereto. In an embodiment, the phase-change metasurface waveguide mode converter includes the plurality of phase-change antennas configured to alternate between a crystalline phase and an amorphous phase.
