Monolithically Integrated Metasurface on a PCSEL for Depth Perception.
Article in Nano letters, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Dot projectors are pivotal for depth perception in modern consumer electronics, from smartphones to extended reality devices, enabling applications in computational imaging, machine vision, and privacy-preserving technologies. However, existing dot projector designs face significant challenges related to their size and power consumption. Here, we demonstrate the first monolithic integration of a metasurface hologram and a photonic crystal surface-emitting laser (PCSEL) to realize a chip-scale structured light projector. This approach achieves unprecedented reductions in both device footprint and power usage, while preserving practical 3D sensing capabilities. Our wafer-level design features a compact footprint of 0.025 mm
