Active tunable WDM demultiplexer with intrinsic gain based on vectorial parametric amplification

Journal article, 2023

We report on the realization of an active tunable wavelength division multiplexing (WDM) demultiplexer based on vectorial parametric amplification in a highly nonlinear bismuth-oxide fiber. The demultiplexing of a 10 Gbits/s WDM channel is demonstrated with little power penalty. The compact device integrates wavelength conversion and filtering functions while providing parametric gain. Furthermore, the proposed scheme could be extended to perform time division multiplexing (TDM) and WDM simultaneously.
