WebWaveguide: 3‑Region Guided‑Mode & Facet‑Reflectance Solver

WebWaveguide is a browser‑based optical waveguide analysis tool for three‑region lossless slab structures. It computes guided TE₀/TM₀ modes, displays their intensity profiles, and evaluates facet reflectance for multilayer coatings.

• TE₀ and TM₀ mode solving with intensity‑profile visualization
• Supports up to three facet‑coating layers
• Modal reflectance data and plots vs. first‑layer thickness
• Total facet reflectance (Vassallo method) for symmetric waveguides
• FWHM and Far Field plots for symmetric waveguides
• TE₀/TM₀ confinement factors and mode indices
• Automatic cutoff detection for both TE₀ and TM₀ modes
• Snapshot feature for saving mode‑profile graphics
