Abstract

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.
