| 摘 要： | The supercontinuum (SC) source plays a key role in wavelength division multiplexing over the optical time division multiplexing (WDM/OTDM) transmission system.The SC produced in dispersion decreasin fibre (DDF) is wider and flatter than that produced in dispersion shifted fibre (DSF).In this paper,a SC producing process in DDF is numerically simulated,the effects of pump pulse chirp on the SC width and flatness are initially studied and the corresponding theoretical explanations are given.Particularly,we have analysed and compared the evolutions of the SC along DDF pumped by different chirp pulses.Several valuable conclusions are obtained.

| Abstract: | The supercontinuum (SC) source plays a key role in wavelength division multiplexing over the optical time division multiplexing (WDM/OTDM) transmission system. The SC produced in dispersion decreasing fibre (DDF) is wider and flatter than that produced in dispersion shifted fibre (DSF). In this paper, a SC producing process in DDF is numerically simulated, the effects of pump pulse chirp on the SC width and flatness are initially studied and the corresponding theoretical explanations are given. Particularly, we have analysed and compared the evolutions of the SC along DDF pumped by different chirp pulses. Several valuable conclusions are obtained. |
