Dynamical effects of optical feedback on InAs- InGaAs quantum dot semiconductor laser

الملخص EN

Quantum dot semiconductor InAs/ InGaAs laser subject to optical feedback is examined.

The effect of control parameters viz.

feedback strength, linewidth enhancement factor, delay time and optical confinement factor are studied.

Rich dynamics are observed ranging from steady state output, oscillatory one in the shape of period one and period two to chaotic one.
