Integrated Brillouin photonics in thin-film lithium niobate.
Article in Science advances, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
Stimulated Brillouin scattering (SBS) is revolutionizing low-noise lasers and microwave photonics. However, a scalable and efficient integrated platform for Brillouin photonics has remained elusive. Here, we leverage the well-established thin-film lithium niobate (TFLN) platform to address these long-standing limitations. We report two distinct SBS processes on this platform, driven by surface acoustic wave (SAW) with 20-megahertz linewidth or bulk acoustic waves with a linewidth 200 times broader. Exploiting the strong SAW SBS gain, we demonstrate a narrowband internal net gain amplifier overcoming propagation losses. In addition, we achieve a stimulated Brillouin laser in TFLN, featuring a tuning range exceeding 20 nanometers and enabling high-purity radio frequency signal generation with an intrinsic linewidth of 9 hertz. Furthermore, we develop a programmable, multifunctional integrated Brillouin microwave photonic processor capable of notch filtering, bandpass filtering, or true time delay. This work bridges SBS with advanced TFLN technologies such as high-speed modulators and wideband optical frequency combs, unlocking new paradigms for integrated Brillouin photonics.
