Investigating the dynamics of quantum well and quantum dot semiconductor lasers in the presence of injection current modulation

Abstract EN

we compare the dynamics of both quantum dot and quantum well semiconductor lasers in the presence of injection current modulation through the variation of level of the dc and ac parts of the injection current and the modulation frequency .

The addition of the third degree of freedom enhances vast range of dynamics ranged from periodic to chaotic .

Obtained results proved the similarities and discrepancies in the dynamics of both lasers.
