RESUMO
We investigate the performance of three different non linear directional assymmetrical fibers couplers that include a profile of self-modulation of increasing and decreasing phase. The asymmetry is associated with the profile of self-modulation of phase of one of the chanels. Initially, we investigate the performance of the considered coupler using ultrashort pulses, type sóliton with 2ps of width and later operating with signal CW. Observing the characteristics of transmission of the device, through the direct chanel and cross chanel, we made a study of the extinction ratio (Xratio) of the devices. The extinction ratio of a switching on-off is the relation among the exit power in the state on and the power of exit in the state off. It was observed that the performance of gates AND, XOR, OR are dependents of the profile of non linearity. In the profile of constant it was not verified that logics AND and XOR present one better performance with the device operating in CW, while logic OR present better with the coupler operating in pulse regime. We conclude that coupler to operate it as logic gate we can control the non-linearity profile to optimize the characteristics of transmission through the extinction ratio.
