Spectral properties of the coherence collapsed state of a semiconductor laser with delayed optical feedback

A theoretical analysis of the coherence collapsed state for a single-mode semiconductor laser with a moderate amount of delayed optical feedback that is operating well above threshold is presented. Both phase fluctuations and the amplitude fluctuations satisfy a bivariate Gaussian distribution. The autocorrelation properties are determined self-consistently from the rate equations. The asymmetry of the optical power spectrum is discussed.<
