Abstract

Static and dynamic characteristics of weakly index guided VCSELs in a multi-transverse mode regime are analysed by using a model that takes into account all the transverse modes supported by the waveguide and a consistent spectral gain including many-body effects. Selection of a particular high order transverse mode by using azimuthal dependent current profiling can be obtained over a wide current range. The alternate current modulation of two orthogonal high order transverse modes is studied taking into account thermal effects. This current induced spatial switching leads to high frequency beam steering in the laser azimuthal direction.
