Paper Abstract

In the present paper, we have carried out analysis of asymmetric light propagation in a chirped photonic crystal (PhC) waveguide. The designed structures have hexagonal arrangement and square arrangement of Silicon (Si) rods in air substrate. Dimensions of the defect rods is tailored, so that the proposed design structure work as an optical isolator. The transmission analysis of the structure reveals that it can act as an optical diode. We have plotted the extinction ratio and transmission analysis graphs for the structure and it has been observed that maximum output is obtained for telecom wavelength of 1.55μm.
