Paper Abstract

Numerical simulations of the spatial dynamics of the light output of 2D arrays of VCSELs are presented. The cases presented include square and circular arrays of nine elements. For both configurations the spacing between elements is varied to study the effects on the interaction between elements. In addition, the effects of index guiding on the supermodes of the arrays will be shown. It was found that, with only a small amount f index guiding, the interactions between elements of the VCSEL array are effectively eliminated for all spacings between elements. The time evolutions of the spatial profiles of the laser intensity and carrier density are obtained by solving the Effective Semiconductor Bloch-Maxwell equations by a finite- different algorithm. The algorithm can handle devices with multiple active regions of nay shapes or pattern. There is no a priori assumption about the type or number of modes.
