Effect of cutoff frequency and proposals for improvement in nagetive electrical feedback semiconductor laser
Computer simulation shows that the rate of linewidth narrowing is limited by the low cutoff frequency (fc) of feedback loop, because of the FM response of usuall semiconductor laser. Somiclagsical theory analysis shows that not only the narrowed linewidth output can be obtained, but also the limits to fc can be canceled by using two-electrode imhomogenous linewidth enhancement factor semiconductor laser. In this paper we present proposals for improvement.
