  2. Mach–Zehnder interferometer - Wikipedia

    en.wikipedia.org/wiki/MachZehnder_interferometer

    The Mach–Zehnder interferometer is a device used to determine the relative phase shift variations between two collimated beams derived by splitting light from a single source. The interferometer has been used, among other things, to measure phase shifts between the two beams caused by a sample or a change in length of one of the paths.

    [13] [14] Their complicated experiment is based on the Mach–Zehnder interferometer, involving a triggered diamond N–V colour centre photon generator, polarization, and an electro-optical modulator acting as a switchable beam splitter. Measuring in a closed configuration showed interference, while measuring in an open configuration allowed ...

  4. Interferometry - Wikipedia

    en.wikipedia.org/wiki/Interferometry

    The Mach–Zehnder interferometer's relatively large and freely accessible working space, and its flexibility in locating the fringes has made it the interferometer of choice for visualizing flow in wind tunnels, [40] [41] and for flow visualization studies in general. It is frequently used in the fields of aerodynamics, plasma physics and heat ...

  6. Interferometric visibility - Wikipedia

    en.wikipedia.org/wiki/Interferometric_visibility

    Visibility in a Mach–Zehnder interferometer is constant. Visibility in this double-slit interference is maximum (80%) at the center. Visibility in Hong–Ou–Mandel interference. At large delays the photons do not interfere. At zero delays, the detection of coincident photon pairs is suppressed.

  7. Delay line interferometer - Wikipedia

    en.wikipedia.org/wiki/Delay_line_interferometer

    A delay line interferometer (DLI) can be a Mach–Zehnder interferometer or Michelson interferometer based on two-beam interference, in which one beam is time-delayed to the other by a desired interval. Delay line interferometers are also known as optical DPSK demodulators. They convert a phase-keyed signal into an amplitude-keyed signal.

  8. Delayed-choice quantum eraser - Wikipedia

    en.wikipedia.org/wiki/Delayed-choice_quantum_eraser

    The construction of solid-state electronic MachZehnder interferometers (MZI) has led to proposals to use them in electronic versions of quantum-eraser experiments. This would be achieved by Coulomb coupling to a second electronic MZI acting as a detector.

  9. Double-slit experiment - Wikipedia

    en.wikipedia.org/wiki/Double-slit_experiment

    The Mach–Zehnder interferometer can be seen as a simplified version of the double-slit experiment. [45] Instead of propagating through free space after the two slits, and hitting any position in an extended screen, in the interferometer the photons can only propagate via two paths, and hit two discrete photodetectors.
