CHAOS SUPPRESSION IN VERTICAL CAVITY SURFACE EMITTING LASER DIODES
We studied the dynamics of Vertical Cavity Surface Emitting Lasers (VCSEL) under high frequency modulation. VCSELs can have a negative gain suppression factor and they can also exhibit self pulsation under appropriate bias conditions. When high frequency modulation is applied a variety of effects in the laser dynamical behaviour can occur, including chaos. The possibility of controlling chaos in a VCSEL laser diode, in order to use chaos control as a useful characteristic, is presented.
