.Pulse-width compression based on photonic crystal fiber[J].Optoelectronics Letters,2006,2(3):206-208 Pulse-width compression based on photonic crystal fiber WANG Jing WANG Zhen-li SHI Yan-mei Institute of Information Science and Engineering, Ocean University of China, Qingdao 266077 ,China 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.
