Abstract
It is experimentally shown that the pattern effect inherent in semiconductor optical amplifiers can be eliminated by using self-assembled quantum dots in the active region. This property comes from the ultrafast response of the dominant gain nonlinearity, or spectral-hole burning, which can respond as fast as <3 ps due to intra-dot carrier relaxation, thereby enabling operation up to 160 Gbit/s.Keywords
