Abstract

Epitaxially grown Nd(0.5%):(Gd,Lu)<sup>2</sup>O<sup>3</sup>and Er(0.6%):(Gd,Lu)<sup>2</sup>O<sup>3</sup>waveguides deposited on Y<sup>2</sup>O<sup>3</sup>by Pulsed Laser Deposition, providing peak emission cross sections comparable with those of Lu<sup>2</sup>O<sup>3</sup>bulk crystals, have been fabricated and structured. Rib waveguiding has been shown.
