Abstract

Based on the transfer matrix method, the spectral characteristics of series-coupled weak ring-waveguide microresonator are investigated. Influences of the internal and external coupling coefficients on the sub-resonant are analyzed. Results demonstrate that the wavelength spacing of mode-split-resonances expands obviously as the internal coupling coefficients of the adjacent rings (K1~KN-1) increasing. By the monitoring the variation of wavelength spacing of the split resonance, photonic sensor with high sensitivity and high reliability is presented.
