Recurrent Optical Spectrum Slicers as multi-λ processors for WDM optical equalization of IM/DD channels
arXiv:2507.11659
Abstract
We report recurrent optical spectrum slicers as multi-wavelength optical processors in dispersion impaired IM/DD transmission systems with the use of programmable photonics. We demonstrate simultaneous equalization of three 64 Gb/s PAM-4 wavelengths after 75 km in the C-band and high tolerance to wavelength grid.
