abstract = {We investigate experimentally and theoretically nonlinear
dynamics and polarization bistability in a vertical-cavity
surface-emitting laser (VCSEL) submitted to an external optical
injection with orthogonal polarization, i.e., the injected light
from a master laser (ML) is linearly polarized and orthogonal to
the polarization direction of the free-running VCSEL (slave
laser, SL). Depending on the injection power level and the
frequency detuning between ML and SL, our experimental results
show that the injected VCSEL may undergo complex dynamics
including subharmonic resonances and period-doubling route to
chaos that are associated to polarization switching (PS). Using
continuation method, we carry out a detailed bifurcation analysis
and report on qualitatively different dynamics as we change the
injection strength and/or the detuning. We show that PS may be
strongly influenced by the presence of those dynamics. Our
numerical results reveal period doubling dynamics that emerge
from a Hopf bifurcation associated to an elliptical polarized
injection locking state. Pure frequency-induced polarization
bistability, i.e., when the detuning is changed for fixed
injection power, is studied theoretically. Our results show that,
depending on the level of the fixed injection strength, frequency
induced PS may be achieved with or without hysteresis. },
