- 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.
