Capacity and SKR tradeoff in coexisting classical and CV-QKD metropolitan-reach optical links
Cagla Ozkan, Lucas Alves Zischler, Kadir Gumus +3
We demonstrate power-regime-dependent guardband optimization for quantum-classical coexistence in metropolitan DWDM. Quantum channel at band-edge with 100-150 GHz guardbands achiev…
One Terahertz Full-Field Digital Back-Propagation over 3000 km
Eric Sillekens, Ruben S. Luis, Giammarco Di Sciullo +14
We implement full-field digital back-propagation with a 1-THz receiver using 20 synchronous frequency-adjacent coherent receivers with digital stitching and a frequency-comb local…
Raman amplification and ISRS in SDM links: Analytical evaluation and closed-form models for optical transmission
Lucas Alves Zischler, Antonio Mecozzi, Cristian Antonelli
In optical communications, the Raman effect is exploited for its lasing properties in distributed Raman amplification (DRA) and leads to spectral distortions through inter-channel…
On the SNR Statistics in Coupled-Core Multi-Core Fiber Transmissions with Mode-Dependent Loss
Chiara Lasagni, Paolo Serena, Alberto Bononi +4
We investigate the impact of mode-dependent loss (MDL) on the statistics of the signal-to-noise ratio (SNR) in coupled-core multi-core fiber (CC-MCF) systems. Through numerical and…
Secret Key Rate Limits in Coexisting Classical-Quantum Optical Links
Lucas Alves Zischler, Amirhossein Ghazisaeidi, Antonio Mecozzi +1
Classical-quantum coexistence enables cost-effective transmission of data and quantum signals over the same fiber-optic channel. Nevertheless, weak quantum-key distribution (QKD) s…
Spontaneous Raman scattering in SDM fibers
Lucas Alves Zischler, Giammarco Di Sciullo, Divya A. Shaji +2
Spontaneous Raman scattering (SpRS) is a weak non-linear effect, particularly relevant to classical-quantum coexistence transmission and sensing applications. In classical transmis…
