TL;DR: QD lasers are thus superior to QW lasers for any system or network, and Quantum dot semiconductor optical amplifiers (QD SOAs) demonstrate gain recovery times of 120–140 fs, 4–7 times faster than bulk/QW SOAs, and a net gain larger than 0.4 dB/(mm×QD layer) providing us with novel types of booster amplifiers and Mach–Zehnder interferometers.

Journal ArticleDOI
TL;DR: The development of SiN x passivation layers have largely mitigated the gate lag effect, however, this passivation layer introduces an additional strain that forms a non-uniform polarization induced charge that can locally relax the film eliminating the piezoelectric induced charge.
