Abstract
In this article, we propose a common photonic crystal based logic gate structure with T-shaped waveguide which can be used as XOR, OR and NOT gates. The inputs are inphase with each other for OR function whereas they are out of phase for XOR and NOT functions. The destructive interference due to out of phase inputs produces a very low output transmission for logic ‘0’ which leads the structure to provide an output contrast ratio of 55.31 dB. Moreover, compared with the existing literature on the photonic crystal based logic gates, the achieved contrast ratio of the proposed structure is improved by more than 23%. Further, the calculated response time is very less with a value of 0.1456 ps which leads to a bit rate of 6.868 Tbps.
