The Influence of Geometric Characteristis on a Bandwidth of the Photonic Crystal Waveguide

Abstract

We investigated the influence of GaAs pillars diameter on a frequency band in the case of 2D photonic crystal waveguide. The obtained result show that the bandwidth changes with changing of the pillars diameter. We also have shown that changing of diameter of pillars in the photonic crystal waveguide structure allows us to design optical filters.
