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

The rapid growth of artificial-intelligence computing demands high-bandwidth and energy-efficient data-center interconnects. Although self-homodyne coherent (SHC) transmission reduces digital signal-processing complexity, its practical deployment is limited by ultrafast state-of-polarization (SOP) fluctuations that destabilize coherent reception. Here we show an ultrafast adaptive polarization controller (APC) based on thin-film lithium tantalate, enabled by the co-design of a photonic chip, a finite-boundary gradient-descent (FBGD) algorithm, and a low-latency real-time control system. The FBGD algorithm incorporates the finite phase boundary directly into the control strategy, enabling reset-free continuous SOP tracking. The implemented APC is validated through both standalone polarization-tracking measurements and a dual-polarization 16-QAM SHC 400-Gbps transmission system. Stable reset-free operation under continuous polarization disturbances is maintained up to 1 Mrad·s⁻¹. These results establish a previously inaccessible operating regime for integrated polarization control and provide a practical route toward ultrafast and reset-free polarization control in coherent optical interconnects and other polarization-sensitive photonic systems.
