Multiplexed rectangular dielectric gratings with multiple narrow-band refractive index filtering and sensing
Abstract We propose a low-loss compound structure consisting of a multiplexed rectangular dielectric grating and a waveguide layer, which can function as multi-band optical filters and sensors in TE and TM polarization by utilizing the resonant mode of the waveguide (WG) and the hybrid SP, respectiv...
