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…
