  Vertical cavity Surface Emitting Laser (VCSEL) diodes emit light in two
polarization modes. The amount of optical feedback is found to influence the
intensities of the emitted modes. We investigate the effect of the amount of
total output polarization feedback and polarization selective feedback on the
intensities of the two emitted polarization modes. A 40 micro seconds
resolution time series correlation analysis is done for different feedback
conditions and investigate the power spectral continuity and onset of chaos on
two polarization modes
