Paper Abstract

We investigate the polarization dynamics of vertical-cavity surface-emitting lasers (VCSELs) when they are subject to a large current modulation, but still operate within the fundamental transverse regime. New, interesting, nonlinear dynamics are unveiled in the two fundamental transverse, orthogonal, linearly polarized (LP) modes of the VCSEL. The intensities of the two LP modes may exhibit in phase time-periodic pulsating dynamics at one of the multiples of the modulation period (subharmonic cascade), but chaotic regimes are also obtained, in whic the LP mode intensities exhibit a combination of inphase pulsing at the modulation time-scale and antiphase dynamics on a slower time-scale. Our results suggest furthermore that, in contrast to conventional edge-emitting lasers, chaotic dynamics in directly modulated VCSELs would appear even for small modulation amplitudes (a few tens of percents of DC current) and small modulation frequencies (hundreds of MHz).
