Modulation Properties of Modulation Properties of Optically Injection-Locked Quantum Cascade Lasers
Abstract : A rate equation analysis on the modulation response of an optical injection-locked quantum cascade laser is
outlined. It is found that the bifurcation diagram exhibits both bistable and unstable locked regions. In addition,
the stable locked regime widens as the linewidth enhancement factor increases. It is also shown that both positive
and negative optical detunings as well as strong injection strength enhance the 3 dB modulation bandwidth by as
much as 30 GHz. Finally, the peak in the modulation response is significantly influenced by the optical frequency
detuning.
