Photizon Benchmarks
What each engine was checked against — the closed form or the published value, our number, the deviation printed as it is, and a link that opens the same calculation.
Looking for what the controls do instead? The Docs are the per-tool operating reference, and the Academy tutorials explain the physics.
Analytic closed forms, cross-validation against an independent open-source implementation, published catalog data, four reproductions from the coating literature, and the optimizer measured against an analytically enumerable root set. Every deviation printed as it is, and most cases open in the simulator with one click.
Closed forms with exact answers, cross-validation against an independent open-source ray tracer, 399 vendor glasses against the makers’ printed index, two patent lenses typed from the original scans, and forty-six defects planted in the engine on purpose to see whether the checks catch them. Every difference printed as it is.
The FDE engine against exact answers for slabs, bends and substrate leakage, against MPB on the tool's preset waveguides and against full-wave Meep simulations of bends, with the free EIM engine on the same cases. Every difference printed as it is.
The FDE engine against an exact answer for two silicon slabs, against MPB on straight silicon and silicon nitride pairs and against 3D Meep simulations of a ring over its bus and of S-bends, with the free EIM engine where it has a model. Every difference printed as it is.
