Abstract

By varying the thulium concentration in the range of 1.5 – 8.0 at.% in thulium- gadolinium-lutetium-yttrium-co-doped monoclinic double tungstate channel waveguides, a maximum laser slope efficiency of 70% with respect to the absorbed pump power was obtained. Further integration of these channel waveguides with on- chip mirrors will combine high slope efficiencies and output powers with narrow-line spectral laser characteristics. A silicon nitride layer was deposited onto a planar thulium-co-doped monoclinic double tungstate layer, and subsequently covered by a metal mask. Strip-loaded, corrugated channel waveguides defined by electron-beam lithography were etched into the silicon nitride layer by means of reactive ion etching.
