Metasurface　polarization　optics　that　consist　of　2D　array　of　birefringent　nano‐antennas　have　proven　remarkable　capabilities　to　generate　and　manipulate　vectorial　fields　with　subwavelength　resolution　and　high　efficiency.　Integrating　this　new　type　of　metasurface　with　the　standard　vertical　cavity　surface‐emitting　laser　(VCSEL)　platform　enables　an　ultracompact　and　powerful　solution　to　control　both　phase　and　polarization　properties　of　the　laser　on　a　chip,　which　allows　to　structure　a　VCSEL　into　vector　beams　with　on‐demand　wavefronts.　Here,　this　concept　is　demonstrated　by　directly　generating　versatile　vector　beams　from　commercially　available　VCSELs　through　on‐chip　integration　of　high‐index　dielectric　metasurfaces.　Experimentally,　the　versatility　of　the　approach　for　the　development　of　vectorial　VCSELs　are　validated　by　implementing　a　variety　of　functionalities,　including　directional　emission　of　multibeam　with　specified　polarizations,　vectorial　holographic　display,　and　vector　vortex　beams　generations.　Notably,　the　proposed　vectorial　VCSELs　integrated　with　a　single　layer　of　beam　shaping　metasurface　bypass　the　requirements　of　multiple　cascaded　optical　components,　and　thus　have　the　potential　to　promote　the　advancements　of　ultracompact,　lightweight,　and　scalable　vector　beams　sources,　enriching　and　expanding　the　applications　of　VCSELs　in　optical　communications,　laser　manipulation　and　processing,　information　encryption,　and　quantum　optics.
