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

The rapid development of artificial intelligence has catalyzed substantial progress in photonic information processing, which requires ultralow-power photonic switches for extensive circuit reconfiguration. Nonvolatile switches with zero static power are promising, but current phase change material approaches face challenges including unreliable durability, high switching energy, complicated fabrication, and compromised scalability. Here, we propose and demonstrate a nonvolatile silicon photonic microelectromechanical system (MEMS) switch enabled by tailored stiction effect based on van der Waals (vdW) force. The device uses a unique split waveguide crossing (SWX) with a push-pull MEMS actuator to efficiently switch the mode propagation. The vdW force between two halves of the combined SWX with zero gap provides reliable nonvolatility. The device features 0.23-decibel excess loss, 44.4-decibel extinction ratio, 200-nanometer bandwidth, and ~1-picojoule theoretical switching energy. Furthermore, excellent scalability is validated by a fabricated high-performance 16 by 16 nonvolatile photonic switch array, which has never been reported before.
