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

Arbitrary ratio power splitters (APSs) play a crucial role in enhancing the flexibility of photonic integrated circuits (PICs) on the silicon-on-insulator (SOI) platform. However, most existing APSs are designed with two output channels, limiting their functionality. In this study, we present a shape optimization method to develop a multiport arbitrary ratio power splitter (MAPS) that enables arbitrary power distribution across three output channels within a compact footprint of 6 µm × 2.7 µm. To validate this approach, two MAPS designs were demonstrated with power ratios of 1:2:1 and 1:2:4. Across a bandwidth range from 1500 nm to 1600 nm, these designs matched the desired power distribution with excess losses (ELs) below 0.5 dB. Experimental results further confirmed the effectiveness of the splitters, with ELs below 1.3 dB over a bandwidth of 1500-1565 nm.
