Bistable and coexisting attractors in current modulated edge emitting semiconductor laser: control and microcontroller-based design

This paper reports on the numerical analysis, control of coexisting attractors and microcontroller-based design current modulated edge emitting semiconductor laser (CMEESL). The stability equilibrium points solitary found is investigated. By varying amplitude modulation density, CMEESL displays periodic behaviors, period-doubling to chaotic behavior, bistability coexistence between limit cycle attractors. destroyed controlled a desired monostable trajectory by means linear augmentation method. In addition, circuit also designed indicate that can be used in real applications. Microcontroller-based outputs analysis results confirm each other.
