Hybrid nanophotonic circuits for on-chip optical selectivity

Selective control of light is essential for optical science and technology with numerous applications. I will review nanophotonic waveguides and integrated couplers used for selective coupling and spatial control of multiple degrees of freedom of light. I will highlight our recent development of hybrid nanophotonic circuits for optical logic operations and on-chip information processing. I will present the design and application of an OAM-controlled hybrid nanowire circuit for optical logic operations including AND and OR gates, as well as of an active hybrid nanophotonic circuit that enables nonlinear optical selectivity based on the spin and OAM of light.
