Nanophotonic chip-space interfaces for multidimensional nonlinear optics.
Article in Nature materials, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Reconfigurable interfaces between confined optical modes in integrated photonic chips and structured light in free space would benefit fundamental optical science and photonic technologies. Here we exploit the anisotropic nonlinear susceptibility tensors associated with thin-film lithium niobate to construct nanophotonic chip-space interfaces capable of generating and multidimensionally engineering structured light via injections of photons to on-chip waveguides. Harnessing the nonlinear Čerenkov radiation in integrated nonlinear microring resonators, we tailor the spatial profile, polarization state, emission wavelength, topological charge and temporal wave packet of structured optical vortices, exhibiting reconfigurability and tunability. To showcase the capabilities of our platform, we use continuous-wave excitation to generate tunable optical skyrmions via the spin-orbit coupling and multistate integrated vortex microcombs in the short near-infrared range via synergistic χ
