Resonance characteristics of TE mode in slotted photonic crystal microring resonator

We propose to construct a microring resonator with a slotted photonic crystal nanobeam and demonstrate its basic resonance characteristics by numerical simulation. Resonance spectra and field localization in the ring at resonant wavelengths are calculated. It is found that in the slotted photonic crystal microring resonator, the optical field of the first passband is well confined in the slot zones between every two holes. Due to the large loss, the quality factor of the structure is less than that of the solid-core waveguide ring with the same parameters.
