Design of a new narrow band channel drop filter based on photonic crystal ring resonator
Authors
Abstract:
In this design an optical ring resonator are embedded between two Horizontal input and output waveguides which has 4 orbitals around the center of the resonator so that each orbital consists of 8 rods with different size in which radius of larger orbitals rods are bigger than radius of smaller orbitals rods. The analysis of simulation results showed the proposed filter has the transmission efficiency 100% at the resonance wavelength of 1550 nm, bandwidth and quality factor are 0.2 and 7753 respectively which proves it is a suitable filter for optical communication applications. Ultra-low bandwidth and high transmission efficiency are the most important advantages of the proposed filter in this study.
