Abstract:
According to the characteristics of high-order solitons, compressed picosecond pulses are numerically simulated in the photonic crystal fiber (PCF), by means of split-step Fourier method. The results show that, PCF enables input pulse with lower peak power to form high-order solitons for the purpose of femtosecond pulse-width compression. For example, 60- femtosecond pulse width was made for 1-ps initial pulse width only over the distance of 2.2 m. Besides, shorter optimum fiber length for compression and higher compression ratio could be obtained on the premise of pre-chirp technique.
