Abstract
Abstract
In this paper, OR and AND logic gate functions are realized in a triangular lattice using two dimensional photonic crystal (2DPC). The proposed design of logic gates are based on the phenomenon of resonance and interference. The OR and AND logic gates are constructed by varying the rod radius and by creating Y-shaped waveguide in the structure. Initially, the OR gate is designed with reference input and without reference input and it’s extended for AND gate. The functional parameters of the logic gates such as response period, bit rate, contrast ratio and field distribution of different logics are investigated through 2D finite difference time domain (FDTD) method. The contrast ratio, response period, bit rate and size of the three input OR gate are 30 dB, 0.52 ps, 1.92 Tbps and 12.6 μm×11 μm, respectively. Similarly, the aforementioned parameters are estimated for two input OR gate, two input AND gate and three input AND gate. The proposed logic gates are highly desirable for integrated optics.
