摘要

Abstract

In the era of artificial intelligence

the computing hardware is of critical importance

with various new modalities explored. Information processing using photons

with abundant intrinsic degrees of freedom

as the carrier could embrace low loss

high speed

low latency

low power consumption

and high parallelism. Here

harvesting the intrinsic frequency channels

we propose and demonstrate a parallel optical computing architecture powered by a soliton microcomb source

a broadband Mach–Zehnder interferometer (MZI) mesh and a parallel MZI mesh computing model. The examinations validate the system's capability to perform over 100-frequency channel multiplexed parallel optical information processing. Both spectral consistency and matrix consistency exceed 0.9. This achievement enables a 100-fold increase (and even beyond) in optical computility through ultra-high parallelism without scaling up the chip size

offering a novel technological pathway for future optical computers.
