The temporal behavior of polarization dynamics was numerically analyzed using the spin-flip model (SFM) 7,. It has been demonstrated previously that the timing jitter of gain-switched semiconductor lasers, such as Fabry-Perot (FP) LDs and distributed feedback (DFB) LDs, could be reduced by an external laser beam injection 17,.
Depending on vcsel chips, there is a side mode corresponding to the orthogonal polarization of the dominant main mode in a separated wavelength of subnanometer.
