Невзаємні властивості модифікованих фотонно-кристалічних хвилеводів

Abstract

Nonreciprocal light transport in a modified photonic crystal waveguide is considered. The symmetry breaking consists of modifying the radii of two rows of rods symmetrically adjacent to the waveguide channel. Free package MEEP is used to simulation the signal propagation in the photonic crystal waveguide. Transmission spectra were obtained for diametrically opposite directions of signal propagation in the modified photonic crystal waveguide. It should be noted that structure under investigation does not contain any gyrotropic elements.
