Názov: Parallel optical computing capable of 100-wavelength multiplexing.
Autori: Yu, Xiao, Wei, Ziqi, Sha, Fangyuan, Wang, Xinyu, Chu, Yanqi, Wang, Zhen, Han, Xilin, Wang, Hongwei, Yi, Shulan, Cheng, Yuhu, Hu, Guangwei, Xie, Peng
Zdroj: eLight; 6/17/2025, Vol. 5 Issue 1, p1-10, 10p
Predmety: OPTICAL computing, WAVELENGTH division multiplexing, ARTIFICIAL intelligence, OPTICAL solitons, INTERFEROMETERS, PARALLEL programming, HIGH performance computing
Abstrakt: 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.
