WebWe present experimental results on nonlinear localization and excitability in an original design of a Vertical Cavity Surface Emitting Laser with intracavity saturable absorber. Depending on the sample temperature, the VCSEL with saturable absorber can be locally bistable or self-pulsing at threshold. In the first case, self-localized states (laser cavity … WebOut-of-equilibrium systems exhibit complex spatiotemporal behaviors when they present a secondary bifurcation to an oscillatory instability. Here, we investigate the complex dynamics shown by a pulsing regime in an extended, one-dimensional semiconductor microcavity laser whose cavity is composed by integrated gain and saturable absorber …
