Influence of Subwavelength Grating Asymmetry on Long-Wavelength Infrared Transmittance Filters
Subwavelength dielectric gratings provide a means of narrowband spectral filtering by coupling to quasi-guided leaky modes, providing a high reflectivity background and narrowband transmittance via Fano resonance behavior. Geometrically asymmetric two-step gratings enable normal incidence filtering...
