Optical logic gates are very important structures required for creating all-optical digital signal processing systems. Optical XOR and XNOR gates can be used for designing optical adders and optical comparators, respectively. In this paper we proposed a novel structure which can be used for simultaneous implementation of optical XOR and XNOR logic gates. The proposed structure was designed using a nonlinear photonic crystal ring resonator. The delay time for XOR and XNOR gates are 1.7 and 3 ps, respectively.
