Redefining the limits of real-time noise cancellation in optical fiber links
Charles A. McLemore, Marco Pomponio, Takuma Nakamura +4
A broad and growing array of applications rely on the faithful transmission of ultrastable optical signals over noisy paths, requiring cancellation of environmentally induced noise…
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…
