abstract = {In this paper, we report on experimental and theoretical
investigation on the nonlinear dynamics of the two orthogonal
linearly polarized fundamental transverse modes of verticalcavity
surface-emitting lasers (VCSELs) under sinusoidal current
modulation. Irregular pulses of the power of individual
polarizations are measured with a period equal to twice the
modulation period. In contrast with individual polarizations,
total power displays regular pulsing at twice the modulation
period. The variability of pulse streams is characterized by
using residence times distributions. We show that the residence
time distributions for individual linear polarizations display an
exponential decay for large values of that time. Those results
are well reproduced by using a theoretical model that includes
spontaneous emission fluctuations. However the previous
qualitative features remain even in the absence of spontaneous
emission noise. Our results therefore suggest that the irregular
polarization dynamics have a deterministic origin and can be
defined as deterministic chaos.}
