Abstract :
In our work we assume that unstable waveguiding is the origin of the pulsed operation in VCSELs. When a mode is better confined in the laser structure, its gain will be higher. If somehow the mode itself could alter the structure in such a way that the confinement is improved, then the mode is able to enhance its own gain, a necessary component for every self-pulsing semiconductor laser. The Kerr effect offers the mode such a possibility.
