Fiber-grating pulse compressor: performance with initially chirped pulses

Numerical simulation of a fiber-grating pulse compressor is performed assuming incident frequency chirped pulses. Characteristic fiber lengths are defined to explain qualitatively the behavior of the compression ratio curves. High compression ratios are not particularly sensitive to the input pulse chirp even for pulses of up to twice the bandwidth limit. The results are presented in normalized form with the help of optical soliton theory and can be used for a wide range of initial pulse widths.
