Frequency-resolved optical gating measurements with a sub-10-fs time resolution demonstrate that optical non-linearities of fluorinated polymers (FPs) enable an ultrafast switching of ultrabroadband wavelength- and time-division multiplexed optical signals in the near-infrared (NM) and shortwavelength infrared (SWIR) ranges. In the NTR region, the operation bandwidth of fluorinated polymer thin-film switches is mainly limited by material dispersion. In the SWIR range, material dispersion of a fluorinated polymer is much weaker. Low group delays (less than 40 attoseconds per 1 mm of polymer thickness per 1 THz of data-packet bandwidth) allow ultrafast optical switching of subpetahertz data packets.
