Abstract

The effects of optical feedback from a phase-conjugate reflector on a semiconductor laser are considered in this paper. It is found that under these conditions, the linewidth of a single longitudinal mode diode laser can only be narrowed, never broadened. This is in contrast to feedback from a conventional dielectric mirror. For a multilongitudinal mode semiconductor laser the lasing envelope is found to be narrowed as well. The optical spectra for these cases is discussed and experimentally demonstrated.
