  Visible wavelengths of light control the quantum matter of atoms and
molecules and are foundational for quantum technologies, including computers,
sensors, and clocks. The development of visible integrated photonics opens the
possibility for scalable circuits with complex functionalities, advancing both
the scientific and technological frontiers. We experimentally demonstrate an
inverse design approach based on superposition of guided-mode sources, allowing
the generation and full control of free-space radiation directly from within a
single 150 nm layer Ta2O5, showing low loss across visible and near-infrared
spectra. We generate diverging circularly-polarized beams at the challenging
461 nm wavelength that can be directly used for magneto-optical traps of
strontium atoms, constituting a fundamental building block for a range of
atomic-physics-based quantum technologies. Our generated topological vortex
beams and spatially-varying polarization emitters could open unexplored
light-matter interaction pathways, enabling a broad new photonic-atomic
paradigm. Our platform highlights the generalizability of nanoscale devices for
visible-laser emission and will be critical for scaling quantum technologies.
