Abstract

The microcavity ring and disk resonators coupled to strongly-guiding waveguides are proposed for VLSI-scale photonic integrated circuits (PIC). Their coupling factors, resonance frequencies, and quality factors (Q) are modeled by finite difference time domain (FDTD) method. Key mechanisms which affect the Q are radiative waveguide bending loss, surface-roughness scattering loss, and the coupling between the cavity and adjacent input/output waveguides.
