RT Journal Article T1 Simplified colorless characterization scheme for coherent receivers in DWDM scenarios using a single interferer A1 Reyes-Iglesias, Pedro José A1 Ortega-Moñux, Alejandro A1 Izquierdo, D. A1 Garcés, Ignacio A1 Molina-Fernández, Íñigo K1 Redes de difracción AB Intradyne coherent receivers, capable of detecting an individual wavelength-division multiplexed channel just bytuning the local oscillator frequency, is of great interest for the development of high-capacity flexible opticalnetworks. Nevertheless, the unavoidable amplitude imbalances inherent to any realistic coherent receiver inducean interference contribution from the self-beating of the coincident channels present at its input. The charac-terization of this degraded colorless reception operation is of fundamental importance, but it usually requires theuse of rather complex experimental setups, especially when the effects of tens of interference channels should beevaluated. In this work we propose a novel experimental setup that only requires the use of a single intenseinterferer to emulate those coincident channels, thus drastically simplifying the characterization process. Inaddition, we develop a general expression for the signal-to-noise ratio of the system that theoretically justifies theintended setup and demonstrate by massive numerical simulations its accuracy in different scenarios. We believethat the proposed approach may contribute to facilitate the experimental characterization of high-performancecolorless coherent receivers PB Elsevier YR 2024 FD 2024 LK https://hdl.handle.net/10630/31237 UL https://hdl.handle.net/10630/31237 LA eng NO P.J.
