Paper Abstract

Signal processing, device oriented, ring-index fibres have a unique capability of transmitting either quasi planar modes for large ring diameters or the second order mode in a quasi single-mode regime at lossy discrimination of the fundamental mode, for small ring diameters. Ring-index fibres can maintain single mode transmission for considerable values of normalized frequency for particular cases of the refractive index profile. Theoretically predicted features of ring-index fibres were confirmed experimentally on the samples manufactured by the author. The ring shape of doped rare earth core gives the possibility to stimulate luminescence from the inside of the fibre. In this paper the ring-core doped with Nd3+ ions fibre is reported. The analysis of dependences between parameters of the core on light propagation in ring-core optical fibres is presented. The ring core is made from silica glasses doped with Nd3+.
