- •
A PbSe quantum dots doped fiber amplifier (QDFA) is demonstrated experimentally for the first time.
- •
The QDFA has an ultra-bandwidth characteristic as high as 120 nm ranging 1250–1370 nm waveband, and ~3.7 dB noise figure.
- •
The QDFA provides a new solution to the growing demand of the broadband fiber amplifiers in DWDM systems.
