High Performance In-Line Er-Doped Waveguide Amplifiers Using Room Temperature Sputtered Er:TeO2 Thin Film

Abstract

Monolithic integrated Er-doped waveguide amplifiers with more than 10 dB net fibre-to-fibre gain under 1480 nm pumping are demonstrated, paving the road for room temperature sputtered Er:TeO2 thin film to CMOS-compatible integrated photonics.
