Chirp signal is a kind of pulse-compressed signal with large time-bandwidth products achieved through linear frequency modulation. It has high resolution in range because of its great bandwidth.
The chirp performance of converted signal in wavelength conversion based on cross gain modulation (XGM) in semiconductor optical amplifier (SOA) was analyzed.
