A novel field recovery technique uses orthogonal field distributions and intensity measurements. This method allows for iterative determination of coefficients, enabling efficient light beam reconstruction.

Area of Science:

  • Optics and Photonics
  • Waveguide Technology
  • Electromagnetics

Background:

  • Arbitrary light beams can be represented as sums of orthogonal field distributions.

Purpose of the Study:

  • To propose a new, efficient method for recovering unknown light beam fields.
  • To demonstrate the feasibility of using waveguide eigenmodes for field decomposition.
  • To simplify field recovery through intensity measurements.

Main Methods:

  • Representing an arbitrary light beam as a sum of orthogonal field distributions.
  • Utilizing waveguide eigenmodes for iterative coefficient determination.
