    Subwavelength high contrast gratings as optical sensing elements
    (Wydawnictwo Politechniki Łódzkiej, 2017) Marciniak, Magdalena; Gębski, Marcin; Dems, Maciej; Czyszanowski, Tomasz
    Subwavelength high contrast gratings (HCG) can be used as high reflective mirrors and can be used as mirrors of vertical-cavity surface-emitting lasers. HCG mirrors can be designed in such a way that they are extremely sensitive to environmental changes - changes in the refractive index of ambient substance or changes in the absorption coefficient may cause changes in mirror reflectivity. This phenomenon can be used to detect liquids and gases. In this paper we present analysis of HCG properties. We consider the various HCG mirror designs and the possibilities of detecting gases and liquids.
