Fiber optic amplifier for wavelengths beyond L-band

Sponsor: Fond rozvoje CESNET, z.s.p.o. 

Principal investigator: Ing. Jan Aubrecht, Ph.D.

Member of the research team from IPE: Jan Pokorný

Project number: 672/2021

From: 2021-05-01

To: 2023-05-31

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.

IPE carries out fundamental and applied research in the scientific fields of photonics, optoelectronics and electronics. In these fields, IPE generates new knowledge and develops new technologies.
