Nonlinear Dynamics in Semiconductor Lasers - Abstract
In this talk I will discuss how nonlinear tools of time-series analysis applied to the observed output signals of various laser systems can provide new insight into the underlying dynamics. I will consider as examples from the dynamics of semiconductor lasers: the sudden polarization switching (PS) occurring in vertical-cavity surface-emitting lasers (VCSELs) , abrupt intensity dropouts induced by self-delayed optical feedback (in the low-frequency-fluctuations LFF regime)  and ultra-high pulses induced by continuous-wave coherent optical injection (optical rogue waves) . I will also discuss temporal correlations in the output of a fiber laser during the laminar-turbulence transition . I will show how nonlinear data analysis tools allow characterizing dynamical transitions and extreme intensity fluctuations.  C.
