Abstract: Abstract In this paper, we developed a theoretical formulation to obtain threshold and reflectivity of optical phase conjugate mode (OPCM) in transversely magnetized semiconductors. Expressions are obtained for threshold value of pump intensity and reflectivity… read more here.

Abstract: We numerically investigate the dynamics of a semiconductor laser subject to phase-conjugate optical feedback. We explore the effects of the laser model and feedback parameters for the generation of time-periodic oscillations of the output power… read more here.

Abstract: We experimentally report the sequence of bifurcations destabilizing and restabilizing a laser diode with phase-conjugate feedback when the feedback rate is increased. Specifically, we successively observe the initial steady state, undamped relaxation oscillations, quasi-periodicity, chaos,… read more here.

Abstract: We analyze experimentally and theoretically the chaotic dynamics generated by a laser diode subjected to phase-conjugate feedback. Phase conjugation is obtained from four-wave mixing in a BaTiO3 photorefractive crystal. We demonstrate that the chaos bandwidth… read more here.
