Advances toward fieldable atom interferometers

Advances in Physics: X, 2022
We review the field of atom interferometer inertial sensors. We begin by reviewing the path integral formulation of atom interferometers and then specialize the treatment to light-pulse atom interferometers and, in particular, gravimeters and gyroscopes.

Quantum twin interferometers. [PDF]

Sci Adv
Quantum-correlated interferometer is an emerging tool in quantum technology that offers classical-limit-breaking phase sensitivity. However, to date, there exists a configurational bottleneck for its practicability due to the low phase-sensing power limited by the current detection strategies.

High-Resolution Optical Fiber Temperature Sensor Based on Draw Tower Grating Array

Sensors, 2022
Ocean temperature monitoring is of great significance to marine fishing, aquaculture, and marine operations. Traditional electric sensors lack the potential to multiplex several sensors, and may suffer from electromagnetic interference.

A nanophotonic interferometer

Nanotechnology, 2023
Abstract The transmission of light through sub-wavelength apertures (zero-mode waveguides, ZMW) in metal films is well-explored. It introduces both an amplitude modulation as well as a phase shift to the oscillating electromagnetic field.
