We study the spectral and dynamical behavior of two identical, mutually delaycoupled semiconductor lasers. We concentrate on the short coupling-time regime where the number of basic states of the system, the compound laser modes (CLMs), is small so that their individual behavior can be studied both experimentally and theoretically. As such it constitutes a prototype example of delay-coupled laser systems, which play an important role, e.g., in telecommunication.Specifically, for small spectral detuning we find several stable CLMs of the coupled system where both lasers lock onto a common frequency and emit continuous wave output. A bifurcation analysis of the CLMs in the full rate equation model with delay reveals the structure of stable and unstable CLMs. We find a characteristic bifurcation scenario as a function of the detuning and the coupling phase between the two lasers that explains experimentally observed multistabilities and mode jumps in the locking region.

Chaotic synchronization characteristics of the vertical-cavity surface-emitting lasers subjected by anisotropic optical injection are numerically investigated. First of all, the synchronization quality of the x-linear polarization (LP) mode and the y-LP mode are both periodically changed with the angle θ between the polarizer and the light axes. Second, in a enough large scale region of the feedback coefficient and the injection current, each LP mode can be obtained good synchronization quality when the angle θ exists in the former half periods region., in the case that their synchronization quality are independent of the polarization states of the lasers output. However, each LP mode can be achieved very instable and inferior synchronized quality, which is caused by the angle θ in latter half periods range.

“…Nowadays, mutually coupled VCSELs have attracted considerable interests due to their important application in bidirectional chaos secure communication fields. Since the first demonstration of chaos synchronization between mutually coupled VCSELs [3], nonlinear dynamics, polarization properties and chaos synchronization of mutually coupled scheme have been studied extensively [4][5][6][7][8][9][10]. Relevant reports have shown that the chaos synchronization characteristics between two mutually coupled semiconductor lasers (SLs) behave in an unstable way due to stochastic noise, and stochastic leaderlaggard synchronization is usually observed in a time dependent manner [11][12][13][14].…”

Based on spin-flip model (SFM), the impacts of mismatched intrinsic parameter on leader-laggard chaos synchronization between two mutually coupled verticalcavity surface-emitting lasers (VCSELs) have been investigated numerically. Results show that, for two VCSELs with identical intrinsic parameter, the switching point of leader-laggard caused by continually varying frequency detuning or injection rate detuning is located at zero frequency detuning or zero injection rate detuning, which indicates that the VCSEL with higher frequency or subject to lower injection level plays a leader role. However, for two VCSELs with mismatched intrinsic parameter, the switched point of leader-laggard will deviate from zero frequency detuning or zero injection rate. Therefore, compared with the results obtained under matched intrinsic parameter, the opposite results have been observed in the range between zero detuning and switching point. Additionally, the offsets of switching point induced by different intrinsic parameters are different, and the influence of line-width enhancement factor is found to be the most significant.
