FDTD Microcavity Simulations : Design and Experimental Realization of Waveguide-Coupled Single-Mode Ring and Whispering-Gallery-Mode Disk Resonators

  title={FDTD Microcavity Simulations : Design and Experimental Realization of Waveguide-Coupled Single-Mode Ring and Whispering-Gallery-Mode Disk Resonators},
  author={S. C. Hagness and D. Rafizadeh and Allen Taflove},
We investigate the properties of highQ, wide freespectral-range semiconductor microcavity ring and disk resonators coupled to submicron-width waveguides. Key optical design parameters are characterized using finite-difference timedomain (FDTD) solutions of the full-wave Maxwell’s equations. We report coupling efficiencies and resonant frequencies that include the effects of waveguide dispersion and bending and scattering losses. For diameters of 5 m, the microcavity resonators can haveQ’s in… CONTINUE READING
