Abstract :
A method of finding self-consistent solutions for the field equation and rate equations has been used to study frequency locking, quasi-periodicity, subharmonic bifurcations, and chaos in gain-guided stripe-geometry semiconductor lasers under high-frequency modulation current. The results show that chaotic behavior arises in unstable semiconductor lasers. The route to chaos is not through period doubling, but rather through quasi-periodicity. The frequency-locked regions have been studied. For lasers whose dynamic response exhibits quickly damped relaxation oscillations, only period-two oscillations have been obtained. The calculated results agree with experiment
