Abstract
We propose a new type of grating-assisted microring (GAMR) structure with Bragg gratings placed on microring´s arms. Two Fabry-Perot resonances interact with microring resonance, resulting in GAMR´s unique amplitude and phase spectra. The structure´s characteristics are analytically studied using coupled mode theory and numerically verified by 2D-FDTD. With proper cavity lengths, GAMR exhibits an electromagnetically induced transparency (EIT)-like spectrum. The ultra-narrow resonance can be used for sensing, modulation, and other applications.
