GONZALEZ-GARCIA, A.; POTTIEZ, O.  e  GRAJALES-COUTINO, R.. Estudio experimental de un láser sintonizable en longitud de onda usando un filtro de Sagnac con selectividad espectral mediante cambios en la temperatura. Rev. mex. fis. [online]. 2010, vol.56, n.4, pp.275-280. ISSN 0035-001X.

We demonstrated experimentally a simple configuration to perform wavelength-tuning and multi-wavelength operation in an Erbium-doped fiber ring laser that includes a fiber-optic Sagnac interferometer as spectral filter formed by 7 m of high birefringence fiber and a symmetric coupler. We analyzed the temperature effect on the Sagnac filter response. Through temperature control, we were able to perform wavelength-tuning and multi-wavelength operation in the laser.

Palavras-chave : Sagnac filter; optical fibers; fiber-optic laser.
