Atomic magnetometry is one of the most sensitive field-measurement techniques for biological, geo-surveying, and navigational applications. An essential process in atomic measurement optical polarization rotation a near-resonant beam due to its interaction with spins under an external magnetic field. In this work, we present design analysis silicon-metasurface-based splitter that have been tailored operation rubidium magnetometer. The metasurface operates at wavelength 795 nm has...
Chemical vapor deposition (CVD) allows growing transition metal dichalcogenides (TMDs) over large surface areas on inexpensive substrates. In this work, we correlate the structure of CVD grown MoS2 monolayers (MLs) SiO2/Si wafers studied by high-resolution transmission electron microscopy (HRTEM) with optical quality revealed in emission and absorption from cryogenic to ambient temperatures. We determine a defect concentration order 1013 cm−2 for our samples HRTEM. To have access intrinsic...
Confocal microscopy is an essential imaging tool for biological systems, in solid-state physics and nano-photonics. Using confocal microscopes allows performing resonant fluorescence experiments, where the emitted light has same wavelength as excitation laser. Theses challenging experiments are carried out under linear cross-polarization conditions, rejecting laser from detector. In this work we uncover physical mechanisms that at origin of yet unexplained high polarization rejection ratio...
We demonstrate a new technology for splitting colors with sub-micron resolution using standard backend processing on 300 mm wafers. The color is tunable via the geometry and can be designed to correspond sensitivity of human eye. result in: higher signal-to-noise ratio, better quality enhanced high-end cameras.
We develop metasurface-based nanophotonic components for polarization rotation and polarimetry of atomic spins in a compact rubidium-based magnetometer.
We report our progress towards a metasurface-integrated atomic magnetometer. Numerical simulation and analysis of the magnetometer performance are presented, along with preliminary fabrication effect imperfection.
We show that confocal microscopy arrangement in conjunction with metallic mirrors or beam splitters enhance the cross-polarization extinction by several orders of magnitude, a view to facilitating detection resonant fluorescence emission.
