We report on the Nd 3+ :Y 2 O 3 ceramic optical channel waveguides produced by ultrafast laser inscription with a “double‐line” scheme. The confocal micro‐luminescence images reveal that the original fluorescence emission properties have not been affected by the laser filamentation, which means the original luminescence features have been well preserved in the waveguide volumes. The fabricated micro‐photonic structures emerge as promising candidates for integrated laser sources. (© 2011 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
