Coherent optical Lissajous states, generated via nonlinear processes like second-harmonic generation (SHG), exhibit unique singular properties. These properties are theoretically explored using non-phase-matched SHG of an ellipse field with a C point.

Area of Science:

  • Nonlinear optics
  • Quantum optics
  • Mathematical physics

Background:

  • Coherent optical states are fundamental in various light-matter interaction studies.
  • Second-harmonic generation (SHG) is a key nonlinear optical process for frequency conversion.
  • Singular optics explores the topological properties of light fields.

Purpose of the Study:

  • To investigate the singular properties of coherent optical Lissajous states.
  • To demonstrate the creation of these states through nonlinear optical processes.
  • To theoretically illustrate these properties using a specific SHG scenario.

Main Methods:

  • Theoretical analysis of nonlinear optical processes.
  • Simulation of second-harmonic generation (SHG).
