Paper Abstract

We have demonstrated an all optical switching by use of pulse trapping in photonic crystal fiber (PCF). A train of four pulses with temporal separation of 1 ps is used as the signal pulses, in which only one pulse is trapped by the soliton pulse in the PCF. The wavelength of the trapped pulse is blue shifted, and thus the trapped pulse can be picked off easily by use of a wavelength filter such as a fiber Bragg grating. In addition, The characteristics of the ultrafast all optical switching are analyzed numerically. The trapping efficiency decreases as the temporal separation increases. The low trapping efficiency impairs the performance of optical switching.
