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

As a frontier in integrated photonics, 2D waveguide mesh-based programmable processors offer compact, reconfigurable platforms. However, conventional Mach-Zehnder interferometer (MZI)-based designs rely on wavelength-agnostic routing, which monopolizes the entire mesh for a single functionality at a time, leaving the wavelength domain untapped and bottlenecking parallel processing. Here, we demonstrate a wavelength-division multiplexing (WDM)-enabled multi-core parallel programmable photonic processor using a reconfigurable hexagonal mesh. Our architecture utilizes MZIs integrated with over-coupled microring resonators as wavelength-selective phase shifters. Exploiting sharp phase transitions, these units achieve 1 THz free spectral range and 4.3 mW/π tuning power. By synergistically integrating spatial and wavelength degrees of freedom, our processor allows a single mesh to host distinct network configurations simultaneously. This enables multi-threaded execution and enhanced functional density, demonstrated through flex-grid WDM, parallel optical computation, and microwave photonic dual-beamforming. This work establishes WDM-enabled processing as a promising route toward large-scale, highly parallel integrated photonic systems.
