Abstract

In this paper, we propose a single photonic crystal structure to implement NOT/XOR/OR optical logic gates using interference phenomenon. The gates are designed as T-shaped waveguides. The filter rods used in the design enhance the contrast ratio by up to 82.25 dB compared with the existing designs reported in the literature so far, and provides a maximum bit rate of 1.567Tbps with a response time of 0.63 ps. The proposed design exhibits minimum power loss, and performance parameters are enhanced compared to existing reported works. Photonic logic gates emerged as a potential substitute for their traditional electronic counterparts due to quick speed, low power consumption, and compatibility with current optical communication networks. The size of the proposed device is 144 μm2, can be used for future optical computing and communications. © The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2024.
