On-Chip Active Supercoupled Topological Cavity.
Article in Advanced materials (Deerfield Beach, Fla.), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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.
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
On-chip photonic resonant cavity plays a critical role in widespread applications including lasing, sensing, and spectroscopy. However, the excitation of these cavities typically relies on evanescent coupling within sub-wavelength distances, limiting flexible and precise chip integration. Here, an on-chip supercoupled topological cavity is demonstrated which is critically coupled at 2.3-wavelength distance from a bus waveguide and remains excited even at 3.2 wavelengths, based on the supercoupling mechanism enabled by the valley vortex flow. Optothermal heating facilitates tunable quality factors and dynamic control of the supercoupling condition, allowing transitions from overcoupling to undercoupling through the critical point. The discovery extends the waveguide-cavity excitation distance to multiple wavelengths, unlocking new possibilities for designing and controlling on-chip resonant devices, including supercoupled lasers, sensors, and modulators.
