Opis:: The spectral properties of reflective mirrors based on a classic design of two-dimensional subwavelength photonic crystal are investigated numerically in the visible wavelength range. These reflectors are meant to be made of silica and silicon nitride. A novel numerical strategy is proposed in order to determine the optimal value of the grating fill factor yielding an efficient level of reflectance through the maximal range of wavelengths.

Opis:: In this study, a polarization selective beam splitter constructed by only a single layer subwavelength multisubpart profile grating is presented. Rigorous coupled-wave analysis is adopted to investigate the properties of the structure. It is shown that for a transverse electric polarized wave, the device demonstrates very high reflectivity (>97%) from 1.46 to 1.58 μm; and for a transverse magnetic polarized wave, at the wavelength of 1.55 μm, it exhibits about 50/50 beam ratio under normal incidence. To evaluate the response of the polarizing beam splitters under variation in structure parameters, we also investigated the fabrication tolerances of the device.
