摘　　要：The commercialization of atomic technologies requires replacing laboratory-scale laser setups with compact and manufacturable optical platforms.Complex arrangements of free-space beams can be generated on chip through a combination of integrated photonics and metasurface optics.In this work,we combine these two technologies using flip-chip bonding and demonstrate an integrated optical architecture for realizing a compact strontium atomic clock.Our planar design includes twelve beams in two co-aligned magneto-optical traps.These beams are directed above the chip to intersect at a central location with diameters as large as 1 cm.Our design also includes two co-propagating beams at lattice and clock wavelengths.These beams emit collinearly and vertically to probe the center of the magneto-optical trap,where they will have diameters of≈100μm.With these devices we demonstrate that our integrated photonic platform is scalable to an arbitrary number of beams,each with different wavelengths,geometries,and polarizations.
