“…The nonlinear optical switches found in the literature take several forms depending on the resonant wavelength and their use in optical applications such as encoders [14,15]. In our case, we have exploited polystyrene as polymeric materials with high non-linearity of the Kerr effect and their refractive index can vary proportionally depending on the intensity of the applied power [29] where:…”

Nowadays, miniaturized optical integrated circuits make a great evolution in optical microelectronics technology. In data processing chains, the need for an ultra-fast all-optical encoder is necessary for a large data transfer. In this work, we have proposed an all-optical encoder structure based on nonlinear 2D photonic crystals with Kerr effect exploiting a nonlinear polymer material of high third-order optical susceptibility. In addition, to generate the telecommunication domain wavelength at 1.55µm, an optimization of the optical-geometry parameters has been realized. Simulations will be performed using plane wave expansion and finite difference time domain methods. The nonlinear effect allows an excellent average contrast ratio of 39.76 db, as the structure requires a very low threshold intensity estimated at 1.5 mW/µm2. The significant power transmitted to the output is equal to 99% and 0.03% of input power equivalent to logic state “1” and logic state “0” respectively. The proposed structure generates a bit rate of 1.92Tb/s, therefore able to adapt with other ultrafast all-optical circuits.

An all-optical NOR gate is implemented using a two-dimensional photonic crystal waveguide. The paper provides a structure of an all-optical NOR gate constructed by introducing a line and point defect. The proposed NOR gate uses a hexagonal lattice structure with E shaped waveguide. The contrast ratio, response time and bit rate of three input NOR gate are 29.59 dB, 0.8 ps and 1.19 Tbps, respectively. The proposed gate is constructed with the operating wavelength of 1550 nm. The structure has been simulated and analyzed using Finite Difference Time Domain (FDTD) and Plane Wave Expansion (PWE) methods. It offers high contrast ratio, better response time with ultra-compact size. Hence it is suitable for high speed optical integrated circuits and switching devices.
