Optical Networks and Interconnects
Carmen Mas-Machuca, Lena Wosinska, Marco Ruffini +1
The rapid evolution of communication technologies such as 5G and beyond, rely on optical networks to support the challenging and ambitious requirements that include both capacity a…
Scalable Federated Learning over Passive Optical Networks
Jun Li, Lei Chen, Jiajia Chen
Two-step aggregation is introduced to facilitate scalable federated learning (SFL) over passive optical networks (PONs). Results reveal that the SFL keeps the required PON upstream…
Bandwidth Slicing to Boost Federated Learning in Edge Computing
Jun Li, Xiaoman Shen, Lei Chen +1
Bandwidth slicing is introduced to support federated learning in edge computing to assure low communication delay for training traffic. Results reveal that bandwidth slicing signif…
High-speed PAM4-based Optical SDM Interconnects with Directly Modulated Long-wavelength VCSEL
Joris Van Kerrebrouck, Xiaodan Pang, Oskars Ozolins +18
This paper reports the demonstration of high-speed PAM-4 transmission using a 1.5-μm single-mode vertical cavity surface emitting laser (SM-VCSEL) over multicore fiber with 7 cores…
Inter-Core Crosstalk in Multicore Fibers: Impact on 56-Gbaud/λ/Core PAM-4 Transmission
Aleksejs Udalcovs, Rui Lin, Oskars Ozolins +12
We experimentally demonstrate the impact of inter-core crosstalk in multicore fibers on 56Gbaud PAM-4 signal quality after 2.5-km transmission over a weakly-coupled and uncoupled s…
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…
140 Gbaud On-Off Keying Links in C-Band for Short-Reach Optical Interconnects
Oskars Ozolins, José Manuel Estaran, Aleksejs Udalcovs +12
We demonstrate 140 Gbaud intensity modulated direct detection dispersion-uncompensated links with Mach Zehnder modulator and distributed feedback travelling-wave electro-absorption…
Digital Radio-over-Multicore-Fiber System with Self-Homodyne Coherent Detection and Entropy Coding for Mobile Fronthaul
Lu Zhang, Aleksejs Udalcovs, Rui Lin +15
We experimentally demonstrate a 28-Gbaud 16-QAM self-homodyne digital radio-over- 33.6km-7-core-fiber system with entropy coding for mobile fronthaul, achieving error-free carrier…
Experimental Demonstration of 503.61-Gbit/s DMT over 10-km 7-Core Fiber with 1.5-μm SM-VCSEL for Optical Interconnects
Lu Zhang, Joris Van Kerrebrouck, Oskars Ozolins +18
We experimentally demonstrate a net-rate 503.61-Gbit/s discrete multitone (DMT) transmission over 10-km 7-core fiber with 1.5-μm single mode VCSEL, where low-complexity kernelrecur…
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…
An Algorithm for Constructing All Families of Codes of Arbitrary Requirement in an OCDMA System
Xiang Lu, Jiajia Chen, Sailing He
A novel code construction algorithm is presented to find all the possible code families for code reconfiguration in an OCDMA system. The algorithm is developed through searching al…
