New waveguide mode equations account for incident light, improving accuracy for isotropic and anisotropic systems. A novel peak-value-search method determines refractive index and thickness without needing air gap thickness data.

Area of Science:

  • Optics and Photonics
  • Waveguide Theory
  • Materials Science

Background:

  • Conventional waveguide models neglect incident light's influence, leading to inaccuracies.
  • Understanding light propagation in waveguides is crucial for optical device design.
  • Anisotropic materials present unique challenges in waveguide analysis.

Purpose of the Study:

  • To develop generalized four-wave-model-based waveguide mode equations that incorporate incident light.
  • To address the limitations of existing models that ignore incident light effects.
  • To introduce a numerical method for solving these new equations accurately.

Main Methods:

  • Formulation of new waveguide mode equations based on a four-wave model, including incident light.
  • Development of a peak-value-search (PVS) numerical method for solving the mode equations.

  • Application of the PVS method to analyze both isotropic and anisotropic waveguide systems.

    • Main Results:

    • The new mode equations accurately describe waveguide behavior by including incident light.
    • The PVS method efficiently solves the equations, yielding precise results.
    • Accurate refractive index and thickness are obtained without prior air gap thickness knowledge.

    Conclusions:

    • The generalized four-wave-model-based equations offer a more complete description of waveguide modes.
    • The PVS method provides a robust and efficient tool for waveguide parameter extraction.
    • This work advances the understanding and modeling of light propagation in various waveguide systems.
