“…Glass 0E containing Na 2 O, SiO 2 , ZnO, Al 2 O 3 and Er 2 O 3 oxide was synthesised following the standard melting process, i.e. melted at 1540°C for 3 h, stirred and slowly cooled down [12,13]. The composition or the melting process of the other glasses, 1E, 2E, 3E and 4E were modified to yield glasses with deliberately different homogeneity.…”

“…As for silicate glasses, Al2O3 is typically used to enhance the solubility and homogeneity of rare earth dopants and to reduce the rate of Er -pairs and clusters formation. Nevertheless, we have shown recently (Ondráček et al 2007;Míka et al 2005 andVytikacova et al 2018), that the presence of ZnO in the glass can also contribute to a substantial enhancement of rare-earth solubility. In this paper, the active channel waveguides, formed in novel types of silicate glasses (GZ4), doped with rare-earth elements and Zn were investigated.…”

We reported on the active channel waveguides, formed in novel types of silicate glasses, doped with rare-earth elements, and Zn were investigated. The silicate glass GZ4 with Er 3+ and Yb 3+ content was studied, and the best doping ratio was estimated about luminescent properties. The composition of the glass samples (GZ4) with the content of 0.25 at. % Er 3+ and 5.0 at. % Yb 3+ and Zn 4.0 at. % resp. 5.6 at. % Zn was optimized. This glass was evaluated as the most suitable material for integrated amplifiers in the telecommunication band of 1 530 -1 565 nm. Other samples were prepared with an active channel waveguides and active planar optical power splitter Y with a splitting ratio of 1x2 by two-step ionexchange Na + -Ag + . Diffusion profiles of the created samples were analyzed by the EMA microscope and compared with the near mode-field distribution measurement results. Afterward, the amplification properties of the designed structures were studied, and the differential gain from 1.2 to 1.6 dB (0.48 to 0.64 dB/cm) was achieved by pumping 200 mW at 980 nm.

Abstract-A set of novel silicate glasses containing ZnO and co-doped with Er 3+ and Yb 3+ was designed as substrates for optical waveguide amplifiers. Characterized by exceptionally low up-conversion, minimum Er concentration quenching and high mechanical as well as chemical stability, the reported glasses can compete with phosphate-based materials typically used in the state-of-art active devices. Straight channel waveguides with propagation losses as low as 0.18 dB/cm were fabricated in these substrates using Ag + Na + and K + Na + thermal ion exchange. Net on-chip gain values of 6.7 dB at 1537 nm were measured and a net fiber to-fiber gain of 5 dB was achieved when pumped at 976 nm. A six-level spatially resolved numerical model of an Er-Yb co-doped active waveguide was developed to analyze and optimize the amplifier performance. Modification of the rare-earth dopant concentration and the channel waveguide geometry was proposed to increase the gain figure and improve the overall amplifier efficiency.Index Terms-Channel waveguides, Er-Yb-doped glass, ion exchange, optical waveguide amplifier.
