| Abstract | ||
| The OR-gate structure is proposed in this paper. It can be constructed in different topologies such as ring resonator, self-collimation, waveguide, and cavity-based structures. Linear and nonlinear materials are used to realize this gate in the literature. The proposed design is formed in a linear photonic crystal square lattice based on ring resonator topology. By applying sensitivity analysis; OR-gate is identified. Minimum area structure and high bit rate are the remarkable characteristics for this design. The minimum size of 56.16 μm2, and the bit rates of 2.5 Tb/s are obtained. The phase shift between the input powers and their effect are examined carefully to achieve two new gates. Comparative table is formed for the OR-gate based on ring resonator topology. This structure is designed, and simulated at 1.55 μm wavelength. | ||
