In this paper we present waveguides made in Niobium Borate glasses doped with Er3+ and Yb3+ ions. These buried waveguides were fabricated by using femtosecond laser writing under double line approach. Propagation performance and index refractive profiles were studied in this work. Finally, simulated guiding structures by using commercial software RSOft were performed in order to test these guiding structures as potential amplifiers systems for optical communication purpose
