We report what is to our knowledge the first observation of erbium fluorescence at the optical communication wavelength of 1.5 μm in a perfluorinated medium. Using a Nd'YAG (355-nm) source, we observed fluorescence of the 4I15/2 - 4I15/2 transition with a peak wavelength of 1.535 μm and with a full width at half-maximum of 28 nm. These results can lead to new active devices that use all-fluorinated polymers.
