Chip-scale optically pumped magnetometry enabled by metasurface polarization beam splitter with high transmission efficiency and extinction ratio

Chip-scale optically pumped magnetometers (OPMs) hold great potential for high-resolution biomagnetic imaging, but their further miniaturization is constrained by the bulky macroscopic optical components conventionally used for polarization detection. However, existing nanophotonic devices designed to replace these bul...
