description

International audience; CRIGF is a new generation of narrowband filter. It consists of subwavelength gratings nearby or upon a waveguide. At the center, a small GMRF (Guided Mode Resonance Filter) or GC (Grating Coupler) coupled radiated & guided mode, then, DBR (Distributed Bragg Reflector) at each side localise mode inside a horizontal Fabry-Pérot cavity. Two PS (Phase sections) are use to fine tune the Fabry-Pérot modes with the grating coupler.
