Distributed gas detection utilizing Fourier domain optical coherence based absorption spectroscopy

Results in Physics, 2019
In this study, a new method called Fourier domain optical coherence based absorption spectroscopy (FD-OCAS) is proposed for distributed gas detection for the first time. Mach-Zehnder interferometer based quasi-distributed structure is developed for proof-

Mach–Zehnder interferometers incorporating electrochromic molecules for controlled single-photon detection

Frontiers in Photonics
One particularly fruitful research in the fields of integrated photonics, carried out by a good number of physicists and engineers, concerns the study of different types of materials to be used to control the detection of photons, if not just single ...

Stabilized fiber-optic Mach–Zehnder interferometer for carrier-frequency rejection

, 2013
We have demonstrated stabilization of a fiber-optic Mach–Zehnder interferometer, with a centimeter-scale path difference, to the transmission minimum for the carrier wave of a frequency-modulated laser beam.

Millicharged dark matter detection with Mach-Zehnder interferometer

Physics Letters B, 2023
If the dark sector exists and communicates with Standard Model through the U(1) mixing, it is possible that electromagnetism would have influence on matter fields in dark sector, so-called millicharged particles (mCPs).

High precision dispersion measurement with a multi-loop Mach-Zehnder interferometer [PDF]

, 2017
We present a dispersion measurement method based on an enhanced Mach-Zehnder white light interferometer. Different optical path lengths are superposed in the reference arm by introducing multiple delay loops in the beam path.

Faint trace of a particle in a noisy Vaidman three-path interferometer

Scientific Reports, 2021
We study weak traces of particle passing Vaidman’s nested Mach–Zehnder interferometer. We investigate an effect of decoherence caused by an environment coupled to internal degree of freedom (a spin) of a travelling particle.
