; Roldán Varona, Pablo; Durán Escudero, Miguel; Rodríguez Cobo, Luis; López Higuera, José Miguel; López-Amo Sáinz, Manuel

(MDPI, 2022) Artículo / Artikulua

This work presents a dual-wavelength C-band erbium-doped fiber laser assisted by an artificial backscatter reflector. This fiber-based reflector, inscribed by femtosecond laser direct writing, was fabricated into a single ...

Sánchez-González, Arturo; Pérez Herrera, Rosa Ana

; Roldán Varona, Pablo; Rodríguez Cobo, Luis; López Higuera, José Miguel; López-Amo Sáinz, Manuel

(IEEE, 2022) Artículo / Artikulua

This work presents an experimental analysis and comparison of the performance of quasi-randomly distributed reflectors inscribed into a single-mode fiber as a sensing mirror both in C- and L-band. Single-wavelength emission ...
