abstract = {We report theoretically on the interplay between polarization
switching and bifurcations to nonlinear dynamics
in a vertical-cavity surface-emitting laser (VCSEL) subject to
orthogonal optical injection. Qualitatively different bifurcation
scenarios leading to polarization switching are found and mapped
out in the plane of the injection parameters, i.e., the frequency
detuning vs injection strength plane. A Hopf bifurcation
mechanism on the two-polarization-mode solution determines the
injection-locking boundaries and influences polarization
switching induced by optical injection. We furthermore report on
a torus bifurcation emerging from a two-linearly polarized LP
mode time-periodic dynamics before polarization switching and
injection locking appear. It corresponds to an interesting
combination of relaxation oscillation dynamics in the x-LP mode
together with wave mixing dynamics in the injected y-LP mode. In
agreement with recent experiments, we unveil a period-doubling
route to chaos that involves both VCSEL orthogonal LP modes. The
corresponding region of chaotic dynamics coincides with abrupt
changes in the polarization switching boundaries in the plane of
the injection parameters.}
