Paper Abstract

Local mode coupling theory is used for the study of the tapered fibres with a variation of the core index along the propagation axis. An application to the diffusion of the fibre dopants during the realization by melting with a CO2 laser is done. The results show that the coupling coefficient between modes can be separated in a sum of two coefficients. The first one is the classic coefficient which takes into account the core radius variation along axis. The second one is reported in order to analyse the index core variation.
