Grating Assisted Couplers (GACs) in Silicon-on-Insulator waveguides are studied numerically and experimentally. Their inclusion in a resonant micro-ring configuration enhances their selectivity and limits the resonance range of the microring. We show that a two-wave model based on coupled-mode theory should be replaced by a four-wave model in order to achieve correct device modeling, if the resonant behavior is of interest. This device has potential application for small footprint, highly selective, wavelength filters and sensors.

Abstract
Grating Assisted Couplers (GACs) in Silicon-on-Insulator waveguides are studied numerically and experimentally. Their inclusion in a resonant micro-ring configuration enhances their selectivity and limits the resonance range of the microring. We show that a two-wave model based on coupled-mode theory should be replaced by a four-wave model in order to achieve correct device modeling, if the resonant behavior is of interest. This device has potential application for small footprint, highly selective, wavelength filters and sensors.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
