Abstract :
We theoretically demonstrate that semiconductor optical amplifiers with self-assembled quantum dots can process high bit-rate optical signals over 40 Gbit/s under gain saturation, and have diverse functions like regeneration, reshaping, multiple-wavelength processing, wavelength conversion, and demultiplexing, which meet with the demand of the next-generation broadband all-optical photonic networks.
