Nonlinear Dynamics of Vertical-Cavity Surface-Emitting Lasers [PDF]

Advances in Optical Technologies, 2011
Nonlinear dynamics of Vertical-Cavity Surface-Emitting Lasers (VCSELs) induced by optical injection, optical feedback, current modulation and mutual coupling is reviewed. Due to the surface emission and cylindrical symmetry VCSELs lack strong polarization anisotropy and may undergo polarization switching.

Polarization switches in vertical-cavity surface-emitting lasers [PDF]

SPIE Proceedings, 2004
The polarization dynamics of a vertical cavity surface emitting laser is investigated as a nonlinear stochastic dynamical system. The polarization switches in the device are considered as activation processes in a two dimensional system with a saddle cycle; the optimal way of switching is determined as the solution of a boundary value problem.
