Design,Simulate XOR Logic Gate Based on Two-dimensional Photonic Crystal

Using a two-dimensional (2D) photonic crystal structure in this research, an XOR logic gate has been designed and simulated through easy fabrication technology. The structure includes two inputs and one output used directly, and by moving two rods at the intersection of the inputs, it prevents the light emission in the input channels when one of them is deactivated. Because of the type of design of the same structure, our outputs have the closest value to those of the applied inputs. In this paper, we have attempted to examine the optical power at the output, so that it has the highest optical power value as compared to the input optical power. The adjacent input channel leakage ratio (AC LR) will also be controlled, so that it has the lowest value. Band structure calculations are made through plane-wave expansion method, and the results indicate that a PBG with a wavelength of 1.26 μm to 1.92 μm has been created that no wavelength can be propagated in the structure within the same interval.
