Peak internal gains of up to 14 dB have been achieved in 5 cm long rib waveguides (2.8 dB/cm) fabricated by co-sputtering of Tellurium and Erbium in an oxygen ambient and reactive ion etching.This work was supported by the Australian Research Council under Discovery Project Grant DP070333.© 2010 Optical Society of America2010-08-3010.1364/OE.18.019192
