Mach-Zehnder interferometer

[′mäk ′tsān·dər ‚in·tər·fə′räm·əd·ər]
(optics)
A variation of the Michelson interferometer used mainly in measuring the spatial variation of the index of refraction of a gas; the device has two semitransparent mirrors and two wholly reflecting mirrors at alternate corners of a rectangle, and half the beam travels along each side of the rectangle. Also known as Mach refractometer.

This concept of gravitational antenna is based on matter-wave interferometry, where a set of free-falling cold atoms accumulates a phase shift following the application of separating plates and mirrors using laser pulses: the transfer of The pulse between the lasers and the atoms leads to a physical separation then a recombination of the atomic waves, and leads to an atomic interferometer configuration roughly analogous to a Mach-Zehnder interferometer in optics.
The performances of all-optical logic XOR and OR gates for 100 Gb/s PSK modulated data signal in SOAs assisted Mach-Zehnder interferometer (MZI) have been numerically analyzed [34, 35].
In the case of grating-based MSF sensors, Bragg gratings (FBGs) [15] and long-period gratings (LPGs) [16] are inscribed along the MSF; meanwhile, for interferometric geometries, different configurations can be used such as the Mach-Zehnder interferometer [17], Sagnac interferometer (SI) [18], Fabry-Perot interferometer [19], or Michelson interferometer [20].
In parallel the Mach-Zehnder interferometer (MZI) is most suitable for this purpose as it effectively combines the structural simplicity, the co-propagation of the launched signals and the low switching energy requirement with the potential for integration and the overall practicality [47].
