Quality Factor Enhancement of Optical Channel Drop Filters Based on Photonic Crystal Ring Resonators
1- Shahid Chamran University of Ahvaz
Abstract: (5249 Views)
In this paper, a channel drop ring resonator filter based on two dimensional photonic crystal is proposed which is suitable for all optical communication systems. The multilayer of silicon rods in the center of resonant ring enables one to adjust resonant wavelength of the ring and enhance power coupling efficiency between ring and waveguide. Refractive index and radius of multilayer rods inside the ring are important factors which help one to enhance the desired output parameters. The proposed structure is capable of presenting high quality factor near 1937 in conjunction with 0.8 nm pass band. The high coupling efficiency 99% is another advantage of the proposed filter.
