Waveglass Mobile

Waveglass Mobile is a native iPad tool for exploring optical waveguides through parametric models, field visualization, and numerical checks. It is designed for learning, teaching, and preliminary design analysis. Planar waveguide modes Solve planar TE and TM modes. Inspect effective indices, mode fields, confinement factors, effective widths, and algebraic residuals. Scalar cross-section modes Explore rectangular channel, rib, and dual-channel cross sections with a scalar eigenmode solver. View intensity and signed fields, effective areas, and basis-order comparisons. TE beam propagation Use a scalar paraxial finite-difference beam propagation method to study straight guides, linear tapers, dual-guide couplers, and cosine S bends. Inspect linear or logarithmic intensity maps, window and core power, and output reference-mode projections. Sweeps and numerical checks Run wavelength sweeps and estimate waveguide group index under a fixed material-index assumption. Compare multiple grids and expanded computational windows to assess numerical sensitivity. Save and export Save and reopen JSON design parameters. Export CSV data, Markdown simulation reports, and PNG intensity images for supported studies. Computation runs locally, with no account required. Model scope Cross-section modes are scalar. Propagation uses a TE scalar paraxial approximation and edge damping. Wavelength sweeps do not include material dispersion. This release does not provide full-vector 3D solving, FDTD, PML, reflection analysis, or complete port S-parameters. Interpret results within these assumptions and check convergence. Requires iPadOS 17.0 or later. Available interface languages: Simplified Chinese and English.
