摘要

In this research, a new structure of the Feynman gate based on two-dimensional photonic crystals is designed and simulated. Our circuit is simpler and smaller because we have not included a ring resonator in its design. The optical propagation time is shortened by not using the resonator ring. Additionally, this structure has increased the speed of data transmission. We used linear and point defects based on the Feynman gate accuracy table while simulating the design. The gate has a working wavelength of 1550 nm, and zero and one are determined by the amount of light that reaches the outputs. These devices make designing processors with high speed and low power consumption possible. By removing the ring resonator from our simulation, we were able to include one of the significant design considerations for optical gates: achieving small dimensions.
