Intense photoluminescence from Er doped chalcogenide thin films fabricated by cothermal evaporation
Erbium doped chalcogenide films were fabricated by cothermal evaporation and demonstrated propagation losses and lifetimes suitable for waveguide amplifiers. The 1490nm pumped Photoluminescence yield is up to ~10x higher than the prior best film material, Er:TeO2.
