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…
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…
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…
