Metasurfaces　offer　complete　control　of　optical　wavefront　at　the　subwavelength　scale,　advancing　a　new　class　of　artificial　planar　optics,　including　lenses,　waveplates,　and　holograms,　with　unprecedented　merits　over　conventional　optical　components.　In　particular,　the　ultrathin,　flat,　and　compact　characteristics　of　metasurfaces　facilitate　their　integration　with　semiconductor　devices　for　the　development　of　miniaturized　and　multifunctional　optoelectronic　systems.　In　this　work,　generation　of　structured　light　is　implemented　at　an　ultracompact　wafer-level　through　the　monolithic　integration　of　metasurface　with　standard　vertical　cavity　surface-emitting　lasers　(VCSELs).　This　work　opens　new　perspectives　for　the　design　of　structured　light　systems　with　compactness,　lightweight,　and　scalability.　Ultracompact　beam　structured　laser　chips　with　versatile　functionalities　are　experimentally　demonstrated,　including　multichannel　beams　array　generation,　on-chip　large-angle　beam　steering　up　to　60　degrees,　and　wafer-level　holographic　beam　shaping　with　a　wide　field　of　view　(about　124　degrees).　The　results　will　promote　the　development　of　compact　light　structuring　systems　with　great　potential　in　3D　imaging,　displays,　robotic　vision,　human-computer　interaction,　and　augmented/virtual　reality.
