We propose a single-particle Mach-Zehnder interferometer experiment in which the path length of one arm can change before each passage of a particle through the interferometer. We demonstrate that this experiment can be used to determine to which extent quantum theory provides a description of the observed detection events that goes beyond statistical averages or to refute a corpuscular model (...

We report that low-loss ridge waveguides are directly written on nanoporous silicon layers by using an argon-ion laser at 514 nm up to 100 mW. Optical characterization of the waveguides indicates light propagation loss lower than 0.5 dB/cm at 1550 nm after oxidation. A Mach-Zehnder interferometer sensor is experimentally demonstrated using the waveguide in its sensing branch, and analytical res...

We report a bound on the relative frequency fluctuations in nonlinear second harmonic generation. A 1,064 nm Nd:YAG laser is used to read out the phase of a Mach-Zehnder interferometer while PPKTP, a nonlinear crystal, is placed in each arm to generate second harmonic light. By comparing the arm length difference of the Mach Zehnder as read out by the fundamental 1064 nm light, and its second h...

In this paper, a low cost 3x3 coupler Mach-Zehnder interferometric optical fibre vibration sensor is proposed. Unlike traditional Mach-Zehnder interferometer with a strain free reference arm, two parallel optical fibres with different strain transfer sensitivity is adopted. With proper demodulation algorithm, the time rate of change of the strain can be computed from the light signal of the out...

We have achieved the design, fabrication and packaging of microfluidic networks with photonic sensors for novel labon-chip platforms which incorporate the on-chip biosensing detection. As sensors, we used an integrated Mach-Zehnder interferometer (MZI) based on TIR waveguides (Si/SiO2/Si3N4) of micro/nanodimensions for evanescent field detection of biomolecular interactions onto the sensing are...

We consider a subgroup of unitary transformations on mode light induced by Mach-Zehnder Interferometer and an algebra observables describing photon-number detector preceded the interferometer. explore uncertainty principles between such their usefulness in performing Bell-like experiment to show violation Clauser-Horne-Shimony-Holt (CHSH) inequality under physical assumption that distinguishes ...

We propose an electronic quantum eraser in which electrons are injected into a mesoscopic conductor in the quantum Hall regime. The conductor is composed of a two-path interferometer, an electronic analog of the optical Mach-Zehnder interferometer, and a quantum point contact detector capacitively coupled to the interferometer. While the interference of the output current at the interferometer ...

Optical fiber Sagnac loop as a interferometer (SLI), is a useful component utilized in devices and systems of optical technology [1,2]. As of today, several components based on SLI, have been designed for applications of wavelength division multiplexing (WDM) filters and optical sensors, using conventional and photonic crystal fibers [3-6]. In an SLI, two interfering waves in an optical fiber l...

The displacement- and frequency-noise-free interferometer (DFI) is a multiple laser interferometer array for gravitational-wave detection free from both the displacement noise of optics and laser frequency noise. So far, partial experimental demonstrations of the DFI have been done in 2D table top experiments. In this Letter, we report the complete demonstration of a 3D DFI. The DFI consists of...

In this paper, a femtosecond laser fabricated fiber inline micro Mach-Zehnder interferometer with deposited palladium film for hydrogen sensing is presented. Simulation results show that the transmission spectrum of the interferometer is critically dependent on the microcavity length and the refractive index of Pd film and a short microcavity length corresponds to a high sensitivity. The experi...
