We　propose　a　method　based　on　metasurface　optoelectronic　integration　to　realize　the　collimation　of　multimode　VCSEL　and　explore　their　polarization　characteristics.　By　integrating　a　metalens　with　a　focal　length　of　630μ　m　on　a　7.5μ　m　oxide　aperture　VCSEL,　we　could　maintain　a　small　divergence　angle　(around　1.73°)　under　different　operating　currents.　The　near-field　beam　intensity　profile　show　that　the　operating　modes　of　VCSEL　with　7.5μ　m　oxide　aperture　are　multi-transverse　modes　distributions.　In　addition,　the　multi-transverse　modes　of　the　VCSEL　are　obtained　by　superpositioning　the　TEM_01　and　TEM_01　modes　with　orthogonal　polarization　directions　through　the　external　polarizer.　This　study　provides　valuable　guidance　for　VCSEL　in　mode　and　polarization　multiplexing,　which　has　potential　applications　in　optical　communication　and　information　encryption　transmission.　©　2023　IEEE.
