Summary:
We numerically study characteristics of dynamical response of a cascaded semiconductor laser system driven by broadband light with randomly fluctuating phase and amplitude. The output light waveform of the cascaded laser system is thoroughly determined by the injected light when the system exhibits a consistent response. We examine frequency components of the injected light that dominantly affect the output. It is shown that components in a particular frequency band dominantly affects the output and the width of this band strongly depends on detunings between two successive lasers in the cascade. We clarify a mechanism underlying this depenence of the bandwidth.
