Before the deposition on the Er:Al2O3 Lively materials, the coupling circuit, i.e., the strip waveguides, the method transition tapers as well as mode converters had been protected which has a 800 nm thick layer of hydrogen silsesquioxane (HSQ, n ~1.45) to avoid their coating with the active materials, as demonstrated in Fig. one. The HSQ clad
