No IDC DURIP Compact System For Trapped Atom Array-Integration on Nanophotonic Circuits
Abstract
Project SummaryProgram Officer: Dr. Roberto DienerResearch Area: Atomic, molecular and quantum physicsPI: Chen-Lung Hung, Purdue UniversityThe purpose of this proposal, #DURIP: Compact system for trapped atom-array integration on nanophotonic circuits,# is to construct a compact ultra-high vacuum system with enhanced capability for realization of programmable optical microtraps for guiding and trapping free space laser-cooled atoms onto a planar nanophotonic circuit. Leveraging a recently developed cold atom loading technique on a nanophotonic resonator, we propose a new system incorporating a compact glass cell and high numerical aperture microscope objectives to form and address a large array of surface microtraps through top and bottom optical projections on a nanophotonic circuit. The system also employs a modular design, separating the atomic source from the science cell, which is equipped with optical fiber and electrical feedthroughs for low-loss coupling and high bandwidth control of photonic resonances for atom-nanophotonic integration. The modular design directly enables fast nanophotonic prototyping and testing with cold atoms. The proposed system will enhance the research program #Alkali-atom optical clock on a photonics-integrated circuit,# funded through the ONR. The DURIP project will also lead to technical advancement towards miniaturizing an atom-nanophotonics integrated quantum system. Approved for Public Release.
