abstract = {In this paper, we summarize our recent results on nonlinear
polarization- and transverse-mode dynamics of vertical-cavity
surface-emitting lasers (VCSELs) induced by optical injection
(OI) or current modulation. Due to the surface emission and
cylindrical symmetry, VCSELs lack strong polarization anisotropy
and may undergo polarization switching (PS). Furthermore, VCSELs
may emit light in multiple transverse modes. This provides new
features to the rich nonlinear dynamics induced in VCSELs by an
external perturbation. We demonstrate for the case of orthogonal
OI that new Hopf bifurcation on a two-polarization-mode solution
delimits the injection locking (IL) region and that PS and IL of
first-order transverse mode lead to a new resonance tongue for
large positive detunings. Similarly, the underlying
polarization-mode competition leads to chaotic-like behavior in
case of gain switching and the presence of two transverse modes
additionally reduces the possibility of regular dynamics.}
