New interferometers generate optical vortex arrays with numerous intensity zeros. These noninteracting vortex arrays prevent annihilation or creation, advancing optical vortex research.

Area of Science:

  • Optics and Photonics
  • Wave Phenomena

Background:

  • Conventional interferometers have limitations in generating complex optical patterns.
  • Optical vortices are characterized by helical phase fronts and carry orbital angular momentum.

Purpose of the Study:

  • To introduce novel interferometric configurations for generating optical vortex arrays.
  • To explore the properties of these generated arrays, specifically their interaction dynamics.

Main Methods:

  • Development of two new interferometric setups.
  • Theoretical analysis and simulation of three-plane-wave interference for vortex array generation.

Main Results:

  • The proposed interferometers produce a large number of isolated intensity zeros, each containing an optical vortex.
