Circular microring-resonator, a symmetric configuration with two straight access channels, strong coupling regime. Parameters: refractive indices 1.0 (background) and 1.5 (cores), bus waveguide width 0.6µm, gap distance 0.3 µm, cavity radius 7.5 µm (outer rim), cavity core width 0.75 µm. |
2-D simulations for TE-polarization, the principal electric field component Ey is perpendicular to the x-z-plane of the computational window.
Transmission properties
Unidirectional HCMT model (hybrid analytical/numerical coupled mode theory), based on the guided slab modes of the access channels,
together with bend modes supported by the cavity core; transmittance

and dropped optical power
D as functions of the vacuum wavelength
