Description
Summary:The limited solubility of rare-earths in silica hampers the development of loss-compensated photonic integrated circuits. We report a novel method using femtosecond laser plasma assisted hybrid material integration of rare-earth-doped tellurite with silica, achieving high doping concentration of Er super(3+) and Yb super(3+)-ions, 1.63 x 10 super(21) atoms.cm super(-3), without segregation validated by Er super(3+): super(4)I sub(13/2) lifetime of 9.1 ms. The sequential ablation of two individual rare-earth (Er super(3+)/Yb super(3+)) doped-tellurite glass targets produces an exceptional intermixing of Er super(3+) and Yb super(3+)-ions extending to the pristine silica with sharp interface. Formation of such homogeneous glass structure with Er super(3+)-Yb super(3+)-ion s in a matrix of silica is not possible to realise by conventional methods.
