We propose a wavefront splitting fiber Mach-Zehnder interferometer (MZI) to achieve such performances. A polyethylene terephthalate (PET) film splits the wavefront of a Gaussian beam emitted from the first fiber collimator. Then, the Gaussian …

WebJan 20, 2024 · * Diffraction Diffraction is a phenomenon in which a wave spreads from the end of a small gap or returns to the shadow of an obstacle. Huygens principle is the principle that countless spherical waves are generated at each wavefront point, and the wavefront of the next moment is created by overlapping the countless spherical waves.

WebDiffraction can be classified as Fresnel or Fraunhofer (also called far field diffraction). In Fraunhofer diffraction the distance between the aperture and the screen is large enough to treat the wavefront as planar.
