Abstract: (1049 Views)
In this paper, a Fredkin gate using photonic-crystal around the 1550 nm telecommunication wavelength is modelled. The proposed structure has a compact footprint compared with previous works of research groups. The proposed structure is based on air holes on silicon substrate. Silicon substrate and air holes have 466 nm and 177 nm radius, respectively. For analyse of the structure Finite-Difference-Time-Domain (FDTD) is applied. To access of nonlinear effects, a glass ring with refractive index of 1.4 and 10-14m2/w is used. To benchmark of the model, response time and contrast ratio is investigated. Numerical results show, in the best case, raise time of 0.21 ps, fall time of 0.02 ps as well as 4.31 contrast ratio can be obtained.
