  2. Mach–Zehnder interferometer - Wikipedia

    en.wikipedia.org/wiki/MachZehnder_interferometer

    The MachZehnder 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.

  3. Electro-optic modulator - Wikipedia

    en.wikipedia.org/wiki/Electro-optic_modulator

    A phase modulating EOM can also be used as an amplitude modulator by using a MachZehnder interferometer. This alternative technique is often used in integrated optics where the requirements of phase stability is more easily achieved. The beam splitter divides the laser light into two paths, one of which has a phase modulator as described above.

  4. Delay line interferometer - Wikipedia

    en.wikipedia.org/wiki/Delay_line_interferometer

    A delay line interferometer (DLI) can be a MachZehnder 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.

    An interferometer is an optical measuring device using the principle of light waves canceling and reinforcing each other. ... e.g. Mach-Zehnder, [1] Michelson, [2] ...

  7. SU (1,1) interferometry - Wikipedia

    en.wikipedia.org/wiki/SU(1,1)_interferometry

    The originally proposed configuration of an SU(1,1) interferometer by Yurke et al. was challenging to realize experimentally due to very low photon numbers expected at the output (for ideal sensitivity) and also the theory did not take into account the internal losses that could affect the phase change sensitivity of the interferometer ...

  8. Beam splitter - Wikipedia

    en.wikipedia.org/wiki/Beam_splitter

    Phase shift through a beam splitter with a dielectric coating. Beam splitters are sometimes used to recombine beams of light, as in a MachZehnder interferometer.In this case there are two incoming beams, and potentially two outgoing beams.

  9. Interferometry - Wikipedia

    en.wikipedia.org/wiki/Interferometry

    The MachZehnder 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 ...
