摘要

Abstract

Recently

there has been growing interest in the miniaturization and integration of atomic-based quantum technologies. In addition to the obvious advantages brought by such integration in facilitating mass production

reducing the footprint

and reducing the cost

the flexibility offered by on-chip integration enables the development of new concepts and capabilities. In particular

recent advanced techniques based on computer-assisted optimization algorithms enable the development of newly engineered photonic structures with unconventional functionalities. Taking this concept further

we hereby demonstrate the design

fabrication

and experimental characterization of an integrated nanophotonic-atomic chip magnetometer based on alkali vapor with a micrometer-scale spatial resolution and a magnetic sensitivity of 700 pT/√Hz. The presented platform paves the way for future applications using integrated photonic-atomic chips

including high-spatial-resolution magnetometry

near-field vectorial imaging

magnetically induced switching

and optical isolation.
