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.
