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.

“…Many researchers have been designed 2D photonic crystal based logic gates and processors such as NAND, NOR, XOR, AND, Adder, Subtractor, Comparator, Encoder, Decoder, Multiplexer etc. [18][19][20][21][22][23][24][25][26][27][28][29][30][31][32]. Comparator is an essential device which is used in CPU and communication system.…”
