Nonlinear dynamics of semiconductor laser emission under variable feedback conditions

A study was made of the behavior of external cavity semiconductor lasers with tilted external cavity mirrors providing variable feedback. The appearance of intermittent breakdowns of the light intensity induced by the tilting of the external mirror is demonstrated. The rate of the breakdowns of the light intensity is directly related to the relaxation oscillation frequency of the external cavity semiconductor laser. The authors describe the experimental observations theoretically by the coupled rate equations for the electric field density and the carrier density.<
