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.
