Chirp frequency response
WebThe carrier density of an SOA will undergo a rapid decrease as a response to an incoming pump pulse, giving rise to a fast red-shifted frequency chirp [58]. The carrier density will then partially recover due to carrier-carrier scattering and carrier heating [59] and then slowly fully recover by electrical pumping.

WebMar 14, 2013 · The chirp signal shows different frequencies at different times but FFT looks the whole signal (all times) and to achieve that I imagine it generates higher harmonics. There is a reason the matlab example plots a spectrogram and doesn't take an FFT and that is because the FFT of the chirp isn't really a generally useful thing to do.
