  • Control of resonant optical evanescent coupling between waveguides and resonators
    Patent number: 12292600
    Abstract: Various embodiments are directed to systems, apparatus and methods for characterizing evanescent coupling parameters of a waveguide coupled to a resonator through variation of their relative positions. Various embodiments extend a local coupling approach with novel fitting capabilities that robustly determine the bare resonator modes and coupling parameters with quantified residual error and coupling parameter uncertainty estimates.
