Abstract :
We present a numerical study of optical signals propagation and switching by using cascaded nonlinear directional couplers based on photonic crystal fibers (NLDC-PCF). We have explored the device´s potential for energy switching by changing the input power for the use of modulated pulses with PAM-ASK. With pulses temporal width of 100 fs, we have considered the influence of high order dispersion effects such as third order dispersion. We have considered too the nonlinear self-steepening, intrapulse Raman scattering and self-phase modulation effects. We have analyzed the device´s transmission of energy efficiency with pump power around the critical power.
