Abstract

We proposed an ultra-broadband multi-sized PbS quantum dots(QDs) fiber amplifier based on a symmetric fused tapered coupler. The 2x2 tapered fiber coupler was coated with a mixture of PbS QDs in two different sizes. By using the multisized PbS QDs as the gain medium, a maximum bandwidth of 400 nm (1200~1600 nm) has been achieved under evanescent wave excitation. In addition, with a 70 mW of 980 nm pump, we obtained a small signal gain of greater than 14 dB in this region.
