Efficient Cholesteric Liquid Crystal Waveguide Polarizing Splitters for High-Sensitivity Chip-Scale Atomic Magnetometry. [PDF]
Adv Sci (Weinh)An integrated polarimetry architecture based on a cholesteric liquid crystal waveguide polarization splitter overcomes the volumetric bottleneck in chip‐scale atomic magnetometers. By leveraging Bragg‐selective reflection and total‐internal‐reflection‐induced helicity inversion, this ultrathin device enables efficient circular polarization splitting ...

Nonzero-Order Resonances in Single-Beam Spin-Exchange Relaxation-Free Magnetometers
Photonics, 2023 Zero-field optically pumped magnetometers operating in the spin-exchange relaxation-free (SERF) regime have been extensively studied, and usually depend on zeroth-order parametric resonance to measure the magnetic field. However, the studies conducted on
