Abstract

We report the first Erbium doped Tellurium dioxide single-mode waveguide amplifiers with net fibre to fibre gain, >40nm gain bandwidth, and a record gain of 2.8dB/cm with 1480nm pumping. We also report the modeled potential gain of 5.4dB/cm for the same device when the amplifier is instead pumped at 980nm and show that higher gains still are within reach.
