Targeting periodic oscillations of external cavity laser diodes.

A simple method of targeting periodic dynamics appearing in semiconductor lasers subject to optical feedback is demonstrated. Possible applications of the technique in chaotic communications are identified, and its advantages for chaos control are discussed.

Dynamical and noise properties of laser diodes subject to strong optical feedback.

Dynamical and noise properties of laser diodes subject to strong optical feedback have been investigated. Under strong optical feedback a conventional rate-equation approach is not valid, and thus an iterative traveling-wave model has been developed to describe this operating regime. Attention has been given to identifying the transition from stable strong-feedback operation to the coherence collapse regime obtained with moderate optical feedback.
