High-Resolution Coherent DFS Over 20km Ultra-Low-Loss Anti-Resonant Hollow-Core Fiber with Live Traffic
Rajiv Boddeda, Arnaud Dupas, Haïk Mardoyan +10
We demonstrate sub-meter resolution Coherent DFS and detect acoustic oscillations using a stabilized laser on 20 km of anti-resonant HCF with <0.10 dB/km loss without impacting liv…
Quantum-Secured DSP-Lite Data Transmission Architectures for AI-Driven Data Centres
Xitao Ji, Wenjie He, Junda Chen +10
Artificial intelligence-driven (AI-driven) data centres, which require high-performance, scalable, energy-efficient, and secure infrastructure, have led to unprecedented data traff…
Attosecond All-Optical Retrieval of Valley Polarization via Circular Dichroism in Transient Absorption
Wenqing Li, Xiaosong Zhu, Pengfei Lan +5
We propose a scheme for retrieving the ultrafast valley polarization (VP) dynamics in two-dimensional hexagonal materials via attosecond circular dichroism (CD) transient absorptio…
Helicity-selected near-circularly polarized attosecond pulses generated from mixed He-Ne gases
Chunyang Zhai, Xiaosong Zhu, Yingbin Li +4
We present and theoretically demonstrate a method for generating helicity-selected near-circularly polarized attosecond pulses in mixed He-Ne gases using bichromatic counter-rotati…
High-purity valley-polarized currents induced by bichromatic optical fields in two-dimensional materials
Wenqing Li, Xiaosong Zhu, Liang Li +4
Producing currents predominantly from a single valley, namely valley-polarized currents, at optical-cycle timescales is an important aspect of the petahertz valleytronics, yet it r…
High Spectral-Efficiency, Ultra-low MIMO SDM Transmission over a Field-Deployed Multi-Core OAM Fiber
Junyi Liu, Zengquan Xu, Shuqi Mo +12
Few-mode multi-core fiber (FM-MCF) based Space-Division Multiplexing (SDM) systems possess the potential to maximize the number of multiplexed spatial channels per fiber by harness…
1002 km Twin-Field Quantum Key Distribution with Finite-Key Analysis
Yang Liu, Wei-Jun Zhang, Cong Jiang +16
Quantum key distribution (QKD) holds the potential to establish secure keys over long distances. The distance of point-to-point QKD secure key distribution is primarily impeded by…
Experimental Twin-Field Quantum Key Distribution Over 1000 km Fiber Distance
Yang Liu, Wei-Jun Zhang, Cong Jiang +15
Quantum key distribution (QKD) aims to generate secure private keys shared by two remote parties. With its security being protected by principles of quantum mechanics, some technol…
Designing wake-up free ferroelectric capacitors based on the superlattice structure
Na Bai, Kan-Hao Xue, Jinhai Huang +8
The wake-up phenomenon widely exists in hafnia-based ferroelectric capacitors, which causes device parameter variation over time. Crystallization at higher temperatures have been r…
All-optical spatio-temporal metrology for isolated attosecond pulses
Lixin He, Jianchang Hu, Siqi Sun +4
Characterizing an isolated attosecond pulse (IAP) is essential for its potential applications. A complete characterization of an IAP ultimately requires the determination of its el…
Accurate Mode-Coupling Characterization of Low-Crosstalk Ring-Core Fibers using Integral Calculation based Swept-Wavelength Interferometry Measurement
Junwei Zhang, Jiangbo Zhu, Junyi Liu +8
In this paper, to accurately characterize the low inter-mode coupling of the weakly-coupled few mode fibers (FMFs), we propose a modified inter-mode coupling characterization metho…
Telecom Compatibility Validation of Quantum Key Distribution Co-existing with 112 Gbps/λ/core Data Transmission in Non-Trench and Trench-Assistant Multicore Fibers
Rui Lin, Aleksejs Udalcovs, Oskars Ozolins +12
We experimentally characterize photon leakage from 112Gbps data channels in both non-trench and trench-assistant 7-core fibers, demonstrating telecom compatibility for QKD co-exist…

Kernel Adaptive Filtering for Nonlinearity-Tolerant Optical Direct Detection Systems
Lu Zhang, Oskars Ozolins, Rui Lin +16
Kernel adaptive filtering (KAF) is proposed for nonlinearity-tolerant optical direct detection. For 7x128Gbit/s PAM4 transmission over 33.6km 7-core-fiber, KAF only needs 10 equali…
