The unique near-field (NF), far-field (FF) and spectral intensity patterns emerging from coherent arrays of bottom emitting proton implanted, medium area vertical cavity surface emitting laser (VCSEL), 10-20 μm in diameter each, are investigated. Each VCSEL is emitting an optical field vortex, the topological charge, and the relative phase. The rich variety of complex supermodes are compared to arrays of regular beams stemmed from this dual charge.
