A polarization sensitive interferometer: Delta interferometer

open access: yesChinese Physics B, 2022
A new type of polarization sensitive interferometer is proposed, named the Delta interferometer, inspired by its geometry resembling the Greek letter Delta. The main difference between the Delta interferometer and other existing interferometers, such as Michelson, Mach–Zehnder and Young’s double-slit interferometers, is that the two interfering paths ...

High-Sensitivity Quantum-Enhanced Interferometers

open access: yesPhotonics, 2023
High-sensitivity interferometers are one of the basic tools for precision measurement, and their sensitivity is limited by their shot noise limit (SNL), which is determined by vacuum fluctuations of the probe field.

Squeezing in Gravitational Wave Detectors

open access: yesGalaxies, 2022
Injecting optical squeezed states of light, a technique known as squeezing, is now a tool for gravitational wave detection. Its ability to reduce quantum noise is helping to reveal more gravitational wave transients, expanding the catalog of observations

A nanophotonic interferometer

open access: yesNanotechnology, 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.
