文摘Here we present the ability of Nd^(3+)-doped zinc-phosphate glasses to be shaped into rectangular core fibers.At first,the physico-chemical properties of the developed P_(2)O_(5)-based materials are investigated for different concentrations of neo-dymium oxide and core and cladding glass compositions are selected for further fiber development.A modified stack-and-draw technique is used to produce multimode large rectangular-core optical fibers.Self-guided nonlinear effects acting as spatial beam reshaping processes occurring in these newly-developed photonic structures lead to the generation of spectral broadenings in the visible and near-infrared spectral domains.
