Abstract

We present a theoretical study of a nanostructured guided-mode resonant (GMR) spectral filter operating in the long-wave infrared (LWIR) wavelength range. The component is made of III-V semiconductors: heavily n-doped InAsSb for the grating and GaSb for the waveguide of the GMR resonator. In order to study the tolerance for the fabrication process and to adjust the resonance of the filter, a geometric study is also presented.
