“…Delayed optical feedback is known to strongly modify the dynamical behavior of semiconductor lasers leading to external cavity mode hopping, periodic or aperiodic dynamics and even coherence collapse [32,33]. Optical feedback impacts the VCSEL's modal properties and dynamics in quite the same way as those of traditional edge-emitting semiconductor lasers [34,35] with the additional peculiarity of introducing polarization switching and two-polarization mode dynamics [36][37][38]. Recently, first studies of CS behavior in optically injected broad-area VCSELs subjected to time-delayed optical feedback have appeared [29][30][31]39].…”

We consider a wide-aperture surface-emitting laser with a saturable absorber section subjected to time-delayed feedback. We adopt the mean-field approach assuming a single longitudinal mode operation of the solitary VCSEL. We investigate cavity soliton dynamics under the effect of timedelayed feedback in a self-imaging configuration where diffraction in the external cavity is negligible. Using bifurcation analysis, direct numerical simulations and numerical path continuation methods, we identify the possible bifurcations and map them in a plane of feedback parameters. We show that for both the homogeneous and localized stationary lasing solutions in one spatial dimension the time-delayed feedback induces complex spatiotemporal dynamics, in particular a period doubling route to chaos, quasiperiodic oscillations and multistability of the stationary solutions.

“…However, the majority of previous studies have focused on the influence of conventional OF on the dynamical characteristics and stability of the VCSELs [5], [10]- [12]. The VCSELs spectral characteristics and their controllable polarization switching (PS) characteristics have also been investigated [13]- [16].…”

“…First studies of VCSELs subject to optical feedback have identified five typical dynamic regimes that have previously been reported in EELs, such as linewidth narrowing or broadening, external-cavity mode hopping, stable laser output, chaotic dynamics, and laser restabilization. 5 However, the polarization properties of VCSELs also lead to new and interesting phenomena when VCSEL are coupled to an external cavity. We can cite, for example, polarization-switching phenomena in polarized optical feedback, 6,7 polarization self-modulation in VCSELs coupled to optical feedback through a quarter-wave plate, [8][9][10][11][12][13][14] optical-feedbackinduced polarization mode hopping, and generalized multistability.…”

Different regimes of low-frequency fluctuations in vertical-cavity surface-emitting lasers

et al. 2003

A numerical study of vertical-cavity surface-emitting lasers with optical feedback demonstrates the existence of two different types of low-frequency fluctuations (LFFs). The competition of two equally dominant polarization modes characterizes one type of LFF, while the other type is characterized by power drops in a dominant polarization mode and power bursts in the orthogonal depressed mode. We characterize and compare these two types of LFFs on the basis of their polarization properties and their dependency on the laser parameters. We show furthermore that a transition is possible from one type of LFF to the other, depending on the values of the linear anisotropies of the vertical-cavity surface-emitting laser cavity.
