Planar Er waveguide amplifier with 8-mW threshold

Abstract

In previous papers,1,2 we reported on waveguide amplifiers fabricated from Er3+-doped sodalime glass films on oxidized silicon wafers. The Er3+ concentration in these films was 4.3 × 1020 Er3+/cc (5.5 wt%) and 2.1 × 1020 Er3+/cc (2.7 wt%). In this work we report on waveguide amplifiers with a lower Er concentration of 0.7 × 1020 Er3+/cc (0.9 wt%) and fabricated via an improved processing technique, which allows the lowest threshold of any waveguide amplifier reported to date.
