HERNANDEZ-ARRIAGA, M.V. et al. Estudio experimental de acopladores bicónicos de fibra óptica aplicados al desarrollo de multiplexores por división de longitud de onda. Rev. mex. fis. [online]. 2018, vol.64, n.1, pp.55-60. ISSN 0035-001X.

An experimental study of the technique of fused biconical fiber couplers for the development of wavelength division multiplexers (WDM) is presented. The fabrication parameters required for the WDM are obtained from the theoretical analysis of the spectral response of a weakly fused coupler. As a particular case, the development of a 1550/1850 nm WDM is reported, which is a fundamental device in the implementation of Thulium-doped fiber lasers. The WDM has the total length of 36.3 mm, and a uniform tapered waist length of 6.5 mm with 23 $\mu$m of cross section. The device exhibits insertion losses of 0.17 dB, a channel spacing of 303.52 nm and a $\pm$ 50 nm bandwidth. This publication could be considered a guide for the development of fiber optic couplers and WDM devices.
