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 ability to detect light with high efficiency is an important device metric for single-photon detectors and cameras, essential for applications ranging from quantum communication to biomedical imaging. However, these photodetectors have limited detection efficiency in the 850-1100 nm wavelength range, known as the 'valley of death'. Here, we demonstrate a near-perfect absorber in the 'valley of death' using a semiconductor metasurface with spectral and spatial selectivity on a high refractive index substrate. Our design leverages higher order optical modes of InGaAs resonators to generate Kerker interference at the target wavelength of 920 nm, which leads to a measured peak absorption efficiency of ∼94%. In addition, numerical calculations show that our design enables spatial control of the absorption profile within the resonators, which is promising for improving response time. Our approach offers tunability over a desired spectral range and paves the way for development of high-performance photodetectors.
