Direct current modulation effects on the photons density InAs InGaAs quantum dot semiconductor laser

الملخص EN

Different dynamics ranging from period 1 to chaos are produced in the photon density PD of InAs/InGaAs quantum dot laser QDL under the effect of injection current modulation using a theoretical model.

Death phenomena in the PD of the QDL was registered too .

Weak and strong modulations of the injection current led to chaotic states.

Bifurcation route appears to be the main route leading to chaos .
