摘要： A hybrid guided-mode resonance (GMR) grating, an optical filter and a method of optical filtering employ distributed Bragg reflection. The hybrid GMR grating includes a waveguide layer that supports a GMR having a GMR resonant frequency. The hybrid GMR grating further includes a diffraction grating that couples a portion of a signal incident on the hybrid GMR grating into the waveguide layer; and a distributed Bragg reflector (DBR) that reflects another portion of the incident signal. The coupled portion of the incident signal has a frequency corresponding to the GMR resonant frequency. The reflected portion has a frequency away from the GMR resonant frequency. The optical filter includes the hybrid GMR grating and a coupler. The method includes coupling an optical signal into the hybrid GMR grating and further coupling a reflected signal out of the hybrid GMR grating.
