Wideband chaos from a laser diode with phase-conjugate feedback

Stability of a diode laser with phase-conjugate feedback.

An exact analysis is presented of the steady-state stability of a semiconductor laser subjected to feedback from a phase-conjugate mirror. Reduced stability occurs at low feedback whenever the effective external delay time is an integer multiple of the relaxation oscillation period. The role of a finite response time of the mirror is to enhance drastically the steady-state stability.

Long-term stable mode locking of a visible diode laser with phase-conjugate feedback.

We present a new method to obtain long-term stable phase-conjugate feedback (pcf) with a photorefractive crystal for a mode-locked semiconductor laser. The phase-conjugate mirror is a barium titanate crystal in a self-pumped internal reflection configuration, and the laser is a visible, antireflection-coated AlGaInP diode. We describe a new dynamic writing procedure for growth of an index grati...

Experimental control of chaos in a laser-diode interferometer with delayed feedback.

Chaos has been controlled with the occasional proportional feedback technique in a delayed optical bistable system that consists of a laser-diode interferometer with a delayed optoelectronic feedback. A variety of subharmonic periodic orbits and high mode oscillations are stabilized at different time delays. No knowledge about the dynamical equation is required for the control. The synchronizin...
