Control of Optical Amplification Process with Extremely Low Background Loss in Er:Al2O3 Waveguides
Demirtaş, Mustafa; Odaci, Cem; Perkgöz, Nihan Kosku; Sevik, Cem; Ay, Feridun (IEEE, 2017)We report on record low-loss single mode a-Al2O3 planar waveguides and growth optimization of a-Er2O3 layers to control erbium-doping level of a-Al2O3 layers realized using Atomic Layer Deposition (ALD). Effect of growth ... -
Design and realization of ALD grown Al2O3 waveguides for applications in silicon based photonics
