ZnO-MgZnO Quantum-Dot Semiconductor Optical Amplifiers

ZnO quantum dot (QD) semiconductor optical amplifier (SOA) is studied theoretically using non-Markovian gain model. SOA performance is then studied by rate equations model. These QD-SOAs have shown to have High gain, low noise figure, and polarization insensitivity. This article appraised patent and patent application related to semiconductor optical amplifier. Keywords: Quantum dot (QD), ZnO, semiconductor optical amplifier (SOA), non-Markovian gain, small-signal gain, rate equations, ground state (GS), excited state (ES), noise figure
