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.

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.
A common-path interferometer is generally more robust to environmental vibrations than a "double-path interferometer" such as the Michelson interferometer or the Mach–Zehnder interferometer. [1] Although travelling along the same path, the reference and sample beams may travel along opposite directions, or they may travel along the same ...
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 ...
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.
Although the design and layout for these types of interferometers can vary depending upon the type of application and corresponding suitable scheme, they all can be mapped to an arrangement similar to that of a Mach-Zehnder interferometer. In this type of interferometry, the input field is split into two by a beam splitter which then propagates ...
The Michelson interferometer and the Mach–Zehnder interferometer are examples of amplitude-division systems. In wavefront-division systems, the wave is divided in space—examples are Young's double slit interferometer and Lloyd's mirror. Interference can also be seen in everyday phenomena such as iridescence and structural coloration. For ...
