The resulting Optical Autocovariance Wind Lidar (OAWL) is a modified Mach-Zehnder interferometer
(Liu and Kobayashi 1996) that uses cat's eye mirrors to increase the interferometer's field of view (Grund and Tucker 2011).

The Mach-Zehnder interferometer
in the SWM is made up of optical fiber with two paths of different lengths.
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)  and long-period gratings (LPGs)  are inscribed along the MSF; meanwhile, for interferometric geometries, different configurations can be used such as the Mach-Zehnder interferometer
, Sagnac interferometer (SI) , Fabry-Perot interferometer , or Michelson interferometer .
Implementation of optical switches using Mach-Zehnder interferometer
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 .
The schematic of our design, both asymmetric and symmetric Mach-Zehnder interferometer
arms switch are displayed in Figures 1(a) and 1(b), respectively.
