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…
Experimental Characterization and Model Validation of Interference in Classical-QKD Coexistence Transmission
Lucas Alves Zischler, Amirhossein Ghazisaeidi, Carina Castiñeiras Carrero +4
We present an experimental characterization of coexistence-induced interference in QKD transmission arising from SpRS and FWM, validating a comprehensive semi-analytical model for…
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…
Accurate and Effective Model for Coexistence of Classical and Quantum Signals In Optical Fibers
Lucas Alves Zischler, Çağla Özkan, Tristan Vosshenrich +10
The rising interest in quantum-level communication has resulted in proposals for coexistence schemes with classical signals within the same fiber optic channel, where the most rece…
Closed-form Expression for the Power Profile in Wideband Systems with Inter-channel Stimulated Raman Scattering
Lucas Alves Zischler, Chiara Lasagni, Paolo Serena +5
Wideband systems experience significant inter-channel stimulated Raman scattering (ISRS) and channel-dependent losses. Due to the non-uniform attenuation profile, the combined effe…
Enabling a multifunctional telecommunications fiber optic network: Ultrastable optical frequency transfer and attosecond timing in deployed multicore fiber
Nazanin Hoghooghi, Mikael Mazur, Nicolas Fontaine +10
The telecommunications industry's deployment of billions of kilometers of optical fiber has created a vast global network that can be exploited for additional applications such as…
