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

Manipulation of laser emission characteristics plays a key role in diverse technologies. However, compact lasers with internal beam steering functionalities remain a challenge. Here, we demonstrate how gradient moiré perovskite superlattices can facilitate dynamic laser beam steering. By combining a two-dimensional (2D) square lattice with a globally curved 1D perovskite grating, we fabricated gradient moiré photonic superlattices with continuously variable twist angles. We revealed how the moiré interlayer coupling at the high-symmetry points on the Brillouin zone boundaries can produce additional cavity modes with twist angle-controlled wave vectors. We showed that the moiré-induced band-edge modes can support lasing with low thresholds. By sweeping the pump area to access different twist angles, we achieved tuning of laser emission angles in a continuous and wide range (>30°) from a single device. Our work provides a highly tunable platform for moiré-induced light-matter interactions, which opens prospects for programmable and intelligent photonic technologies.
