Abstract
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 science and technology frontiers. We
experimentally demonstrate an inverse design approach based on the
superposition of guided mode sources, allowing the generation and
complete control of free-space radiation directly from within a single
150 nm layer , 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 the potential
for 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.
