Abstract

We present novel orbital angular momentum (OAM) modes from a 2x1 coherently coupled VCSEL array. An 8-phase spiral phase plate is used on both elements to generate coupled OAM modes. Far-field mode profiles calculated using Huygens principle are distinctly different for independent versus coherent operation.
