Effect of a defect on the cavity eigenfrequencies. (a) Schematics of a microring resonator and a 2D photonic crystal cavity and corresponding mode field intensities in the azimuthal/longitudinal directions. The grey “cloud” represents a defect. (b) Consequence on the eigenfrequencies ω (red arrows). Horizontal green lines show the same (different) spectral shift δω ( δω,k ) in the resonance frequencies for ring resonators (PhC) caused by the defect on the top (bottom) figure, depending on the spatial profile of the modes.
