A Brillouin fiber laser at 2 µm based on a step-index tellurite (TeO2) optical fiber

Résumé

We demonstrate Brillouin lasing at 2-µm using a step-index Tellurite-glass optical fiber in a passive fiber ring cavity. A low lasing threshold of 70 mW was achieved with a Brillouin gain of 1.05 × 10-10 m/W for a Brillouin frequency shift of 6.165 GHz. Stimulated Brillouin scattering (SBS) in optical fibers is a nonlinear process with important applications such as distributed optical fiber sensing, microwave photonics, optical storage, and fiber lasers. The latter application has attracted significant interest as highly coherent laser sources with sub-Hz linewidth can be achieved using SBS in optical cavities. To date, most of Brillouin fibers lasers (BFLs) have been designed at 1.55 µm. However, for many applications in the mid-infrared region, there is a need to develop laser sources at longer wavelength range.
