Design and analysis of 2D photonic crystal based all optical comparator

Year: 2024

Type: article

Abstract: In this article we have presented all optical comparator using 2-D photonic crystal of silicon poles with dimensions 10a×12a. The structure of this device is very simple having small footprint of nearly 62 µm2. All-optical comparator has been validated by employing finite-difference-time-domain (FDTD) method. We have analyzed this device to calculate the ER, CR and Q value and verified the output by optical field distribution and amplitude with frequency. The performance of the all optical comparator has been investigated by calculating the variation of ER,CR, Q and transmission ratio with wavelength of the input signal and rod radius.
