Properties of erbium and cerium co-doped TeO 2 thin films fabricated by reactive co-sputtering for waveguide amplifier

Vu, Khu; Zhang, Jian-Guo; Madden, Steve


Recently, we reported a high gain planar waveguide amplifier in Erbium doped TeO2 pumped at both 1480nm and 980nm [1, 2]. The performance of the amplifier pumped at 980nm was better than that at 1480nm as generally expected due to the non-resonant pumping. The high gain in a 980nm pumped Er:TeO2 waveguide amplifier led to lasing with only facet reflections. However, the performance of the 980nm pumped Er:TeO2 amplifier was still much lower than theoretical predictions due to the presence of...[Show more]
