Estudo do dispositivo não-linear formado com acopladores de fibra de cristal fotônico dual-core.

This paper presents the study of the performance of an all-optical device based on nonlinear directional couplers based on photonic crystal fiber dual-core. It analyzed the power transmission factor between the waveguides based on three main factors: input power, phase offset and length of the couplers. The numerical study used the Runge-Kutta fourth order to solve the pair of coupled mode equations considering the nonlinear effects of self-phase modulation, cross phase modulation, Raman intrapulse, self-steepening. In addition to the linear effects of second and third order dispersion.
