The dynamical characteristics of InAs InGaAs quantum dot semiconductor laser under optical feedback

الملخص EN

We study the effects of optical feedback on the dynamics of InAs / InGaAs quantum dot semiconductor laser via the use of five equations model that describe the dynamics of such lasers and the addition of a new term that takes into account the effects of feedback and six equation concerning the phase of the electric field.

The effect of a number of control parameters viz optical feedback strength, phase shift and round-trip time of light in the external cavity is being tested.

Rich and varieties of dynamics appeared to occur ranging from periodic to chaotic ones.
