Interference measurements confirmed a temporal correlation vortex in polychromatic light. Topological dispersion was observed to destabilize this singularity, impacting light propagation characteristics.

Area of Science:

  • Optics and Photonics
  • Quantum Optics

Background:

  • Partially coherent light sources are crucial in various optical applications.
  • Understanding the behavior of light correlations is essential for advanced optical phenomena.

Purpose of the Study:

  • To experimentally verify the existence of a temporal correlation vortex in polychromatic light.
  • To investigate the effect of topological dispersion on this vortex.

Main Methods:

  • Interference measurements were performed using a polychromatic partially coherent light source.
  • Analysis focused on identifying and characterizing the temporal correlation vortex.

Main Results:

  • The presence of a temporal correlation vortex was experimentally confirmed.
