Realization of XOR and OR Logic Gate with One Configuration in the Two-dimensional Photonic Crystals
Based on the theory of light beam interference effect, a new configuration is de signed to realize two types of all-optical logic gates including XOR and OR logic gate in two-dimensional (2D) photonic crystals, and the distribution of the electrical field is simulated by the Finite-difference in time-domain method. The results show that through this new configuration, not only the two types of all-optical logic gates can be realized, but the higher light contrast ratio of the logic state 1 and 0 can also be obtained. The realization of two types of all-optical logic gates in one configuration is helpful and significant to the optical device integration and potential in the optical communications. It is noticed that the logic state of 1 and 0 at output port are defined as the transmission is larger than 0.5 and less than 0.1, respectively.
