Abstract:An on-chip multi-grating device is proposed to interface single-atoms and integrated photonic circuits, by guiding and focusing lasers to the area with ∼10 µm above the chip for trapping, state manipulation and readout of single Rubidium atoms. For the optical dipole trap, two 850 nm laser beams are diffracted and overlapped to form a lattice of single-atom dipole trap, with the diameter of optical dipole trap around 2.7 µm. Similar gratings are designed for guiding 780 nm probe laser to excite and also collec… Show more
