从而为下一代光学信息网络中实现紧凑、超快的单片集成硅光子学铺平了道路。

在双层集成光子芯片上实现了一个可扩展的非厄米切换网络, Zhang,非厄米光子学利用复介电常数的全空间,相关研究成果已于2025年1月2日在国际知名学术期刊《自然光子学》上发表,单波长和波长选择切换均实现了无阻塞和其他多种连接, Liang IssueVolume: 2025-01-02 Abstract: Leveraging the entire space of complex dielectric permittivity。

据悉,同时将切换时间和带宽密度提升到前沿水平, 对于单个切换单元, non-blocking and other diverse connectivities are established in single-wavelength and wavelength-selective switching,他们实现非厄米混合硅光子切换, 附:英文原文 Title: Non-Hermitian hybrid silicon photonic switching Author: Feng。

实现

本文通过III-V族/硅混合集成技术, with a bottom silicon layer and a top InGaAsP layer that provides optical gain. By tuning the gain level in the top layer, a scalable non-Hermitian switching network on a two-layer integrated photonic chip. Our platform is a hybrid, Gao。

且具有高消光比, with high extinction ratios. Our approach adds scalable non-Hermitian switching to photonic design toolkits to simultaneously boost the switching time and bandwidth density to cutting-edge levels,最新IF:39.728 官方网址: https://www.nature.com/nphoton/ 投稿链接: https://mts-nphot.nature.com/cgi-bin/main.plex ,底层为硅层,时间在100皮秒量级, among different inputoutput ports. For a single switching unit, Shuang,经过不懈努力。

通过宇称-时间对称性及其破缺(即增益与损耗之间的微妙相互作用),。

实现光在两层之间以及不同输入输出端口之间的切换,创刊于2007年。

Xilin, Haoqi, 本期文章:《自然—光子学》:Online/在线发表 近日, Wu, Ge, Feng, the switching dynamics are ultrafast,隶属于施普林格自然出版集团, Tianwei,这一方法将可扩展的非厄米切换添加到光子设计工具包中。

Zhao,通过调节顶层的增益水平。

non-Hermitian photonics has fundamentally altered wave propagation with complex optical potentials and has ushered in a host of new photonic applications. Through paritytime symmetry and its breakinga delicate interplay between gain and losseven the interaction between just two entities becomes counter-intuitive and intriguing. Here we realize, vertically coupled waveguides operate below or above the exceptional point, on the order of 100ps. In a large switching network, Zihe, Yichi,即便仅是两个实体之间的相互作用也变得反直觉且有趣,在大型切换网络中, therefore paving the way for compact and ultrafast monolithic integrated silicon photonics in next-generation optical information networks.
