CHAOS CONTROL BY DIRECTLY MODULATED OPTO ELECTRONIC FEEDBACK IN SEMICONDUCTOR LASER 
Date: Oct, 2016
Nonlinear dynamic behavior of a directly modulated delayed optoelectronic feedback semiconductor laser has been studied numerically. The variation of small window of modulation current with the delayed optoelectronic feedback produces chaotic behavior of the laser output. The dynamics is completely determined by the variation of the injecting modulated amplitude (A). The chaotic spiking was observed at (A = 0.060). Excitability of the laser diode under directly modulation current with GHz was demonstrated by bifurcation diagram so the modulation amplitude is sensitive in output dynamic of the laser diode.
