Abstract: A filter may include a first component filter associated with a first angle shift and a first passband. The filter may include a second component filter associated with a second angle shift and a second passband, wherein the first angle shift, the first passband, the second angle shift, and the second passband are configured to make the filter transmissive to a spectral range of light at a first angle of incidence and reflective to the spectral range of light at a second angle of incidence.

Abstract: An optical filter having a passband at least partially overlapping with a wavelength range of 800 nm to 1100 nm is provided. The optical filter includes a filter stack formed of hydrogenated silicon layers and lower-refractive index layers stacked in alternation. The hydrogenated silicon layers each have a refractive index of greater than 3 over the wavelength range of 800 nm to 1100 nm and an extinction coefficient of less than 0.0005 over the wavelength range of 800 nm to 1100 nm.

Abstract: An optical filter, a sensor device including the optical filter, and a method of fabricating the optical filter are provided. The optical filter includes one or more dielectric layers and one or more metal layers stacked in alternation. The metal layers are intrinsically protected by the dielectric layers. In particular, the metal layers have tapered edges that are protectively covered by one or more of the dielectric layers.
