1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Conventional waveguide optical resonators face inherent limitations of low damage thresholds, limited coupling tunability, and stochastic resonance. To overcome these, we introduce a geometrical-optics resonator (GOR) framework, emulating free-space reflection and thin-film coupling on-chip. Using ultra-wide waveguides with total internal reflection (TIR) mirrors and frustrated-TIR couplers, GORs eliminate conventional constraints. Fabricated devices achieve intrinsic Q-factors >1 million and enable tunable microwave photonic filters operating distortion-free at about 10× higher optical power. Design flexibility allows precisely tuned coupled resonators, facilitating cascaded networks for spectral engineering. Demonstrated GOR photonic molecules exhibit dynamically adjustable mode splitting (0.49 free spectral range), nearing theoretical limits. The platform also realizes record-large-scale Floquet topological photonic insulators with 1281 GOR lattices, supporting robust edge modes against defects and a broadband continuum. The GOR sets new performance benchmarks, enabling scalable platforms for quantum simulation and topological networks while driving integrated photonics toward higher density and system-level integration.
