Дисперсійні характеристики та тгц вихроподібні моди фотонного кристала антимоніду індія (InSb)

Abstract

We consider dispersion characteristics and field distributions of TE modes in the two-dimensional photonic crystal based on the square lattice of InSb rods. Finite element calculations are used for theoretical investigation of eigen modes of the semiconductor photonic crystal. Effect of the rod’s radius and external magnetic field on the photonic crystal band diagram has been analyzed. The study of spatial field distributions in the periodic structure made it possible to detect modes with amplitude and phase characteristics inherent to optical vortices.
