Abstract

High quality KY1-x-yGdxLuy(WO4)2 lattice matched layers activated with Er3+ and Tm3+ have been grown by liquid phase epitaxy on KY(WO4)2 substrates. From these active layers, we have fabricated channel waveguides by dry etching of their surface through Ar ion milling. The effects on the confinement and overlap of pump and laser modes and on the optical losses of the waveguides due to a cladding layer with the same composition of the substrate grown on these microstructured waveguides have been analyzed. The results clearly show the beneficial effects that this strategy presents, such as a better confinement, a better overlap and specially reduced optical losses when compared to the surface channel waveguides.
