Abstract

We demonstrated optical amplification in BaYF5: 20% Yb3+, 2% Er3+(BYF) nanocrystals doped polymer waveguide. BYF nanocrystals with an average size of ∼13 nm were synthesized by a high-boiling solvent process. Intense 1.53 μm fluorescence was obtained in the nanocrystals under excitation at 980 nm. An optical polymer waveguide was fabricated by using BYF nanocrystals doped SU-8 polymer as the core material. A relative optical gain of ∼10.4 dB at 1525 nm was achieved in a 1.1 cm long waveguide for an input signal power of ∼0.09 mW and a pump power of ∼212 mW.

Highlights

Erbium doped fiber amplifier (EDFA) is considered as the most deployed fiber amplifier as its amplification window coincides with low loss telecommunication windows at 1550 nm

Summary

Introduction

Erbium doped fiber amplifier (EDFA) is considered as the most deployed fiber amplifier as its amplification window coincides with low loss telecommunication windows at 1550 nm. Until recently there are only a few reports on obtained optical gains based on inorganic nanocrystals doped polymeric optical waveguide amplifiers.
