“…The 'Bias' port is always activated to operate our device when both the 'Input 1' and 'Input 2' ports The normalized steady-state power and the contrasts of the 0 and 1 logics for 'XNOR' gate are summarized in Table 7. According to Table 8, it can be concluded that the proposed 'XNOR' structure is characterized by a very high contrast ratio with an ultra-compact size than any previous work (Elhachemi and Rafah 2020;Rao et al 2020b;Xiao-Wen et al 2018;Moniem 2017). This feature is a very important advantage for optical devices.…”

All-optical logic gates are indispensable elements in optical devices and optical computing. Our logic gates are based on bidimensional photonic crystals, where the pillars radius and lattice constant are chosen in such a way that the logic gates are actuated at the wavelength of 1550 nm. The contrast ratios for the NOT, XOR, NOR, and XNOR gates are 26.82 dB, 26.77 dB, 8.34 dB, and 20.17 dB respectively. The response time of the different logic gates is approximately 8.5 ps, resulting in a data transmission rate of 0.117 Tb/s. One of the advantages of our study, from the logic gate NOT we could design all the other gates such as XOR, NOR, and XNOR.

In this paper, we are going to propose a novel structure of all-optical NOT, XOR and XNOR logic gates are presented using a two-dimensional photonic crystal (2D-PhC). This structure is optimized by varying the radius of the cavity, to obtain a quality factor Q = 1192, and also has several ports of entry and one port of output. The size of each structure is equal to 85.8 μm2. The contrast ratios for the structures proposed all-optical NOT, XOR and XNOR logic gates between levels “0” and “1” are, respectively, 25.08, 25.03, and 14.47 dB. The response time for the three logical gates is 8.33 ps, and the bit rate is calculated at about 0.12 Tbit/s, all simulations are based on both numerical methods such as finite difference time domain (FDTD) and plane wave expansion (PWE). Designed logic gates are characterized by low power consumption, compactness and easy integration.
