In the period 5/2021–5/2023, in cooperation with the CESNET Development Fund, a project to develop fiber amplifiers for wavelengths beyond the L band in the spectral range of 1650–2050 nm was successfully implemented. As part of the project, a thulium-doped optical fiber with a suppressed refractive index around the core was produced, which preferentially amplifies signals at shorter wavelengths of the emission spectrum of thulium fibers.
