Chaotic parallel synchronization of optoelectronic feedback semiconductor lasers

A chaotic parallel synchronization model of optoelectronic feedback semiconductor lasers is proposed. The complete synchronization and generalized synchronization are studied，while the effect of intrinsic parameter mismatch on the difference in the synchronization performances between the drive laser and receive laser or between the parallel receive lasers is emphatically discussed. The results show that zero-time-lag complete synchronization between the drive laser and parallel receive laser can be realised under parameter match. For generalized synchronization，if one of the intrinsic parameters of the receive laser is changed，the cross correlation between the parallel receive lasers is larger than thatbetween the drive laser and the receive laser over a wide parameter mismatch range.
