Abstract

A simple adjustment of the “Lang and Kobayashi” delayed rate-equations which describe the dynamics of an external-cavity semiconductor laser is shown to predict low-frequency resonances in the output intensity spectrum of the system. Numerical simulations with control parameter values-driving current and feedback strength-corresponding to our experiments show excellent agreement with theory. A possible mechanism for the occurrence of low-frequency self-oscillations is also proposed
