Abstract

Eight-wavelength Er-doped fiber lasers with lasing wavelength separations approximately 1.6 nm and approximately 0.8 nm, respectively, have been achieved by using a Cascaded fiber Bragg grating (CFBG) in the fiber lasers and cooling the Er-doped fiber with liquid nitrogen. Our experiment shows that, utilizing the CFBG to select the lasing wavelengths, it is convenient to achieve fiber lasers with lasing wavelengths and lasing wavelength separations matching the ITU (International Telecommunication Union) channel allocation grid well.
