  • Abstract
    The authors theoretically investigated the cross-gain modulation and the related cross-phase modulation in a travelling wave quantum dot-in-a-well (QDWELL) semiconductor optical amplifier (SOA). They show that the strong enough pumping wave with an optical power in the range of 1 mW up to several milliwatts synchronises the carrier dynamics in the QDWELL SOA, increasing its operation rate to the frequency of 240 Gb/s and decreasing the patterning effect and chirp.
