Optical switching using optical Kerr non-linear effect on photonic crystal fiber

This paper describes the results of the investigation of nonlinear propagation of short optical pulses in a photonic crystal fibers. It has been observed that nonlinear intensity-dependent effect can be used to determine the transmission and rejection of propagating pulses. The optical switching is achieved using Kerr nonlinear effect to shift the band gap in the Photonic crystal fiber. It is found that high intensity pulses and large nonlinearity effect is essential to allow easily discrimination between ON and OFF states.
