Modeling and Design of Photonic Crystal Quantum-Dot Semiconductor Optical Amplifiers

摘要: A novel design of electrically pumped photonic crystal quantum-dot semiconductor optical amplifiers (PC-QDSOAs) is presented in this paper. Therefore, we a single-mode flat-band slow light waveguide (SL-PCW) for an InAs/GaAs QDSOA which the pumping done by passing current through laterally doped p+–p–n+ structure. In addition, first time to our knowledge, propose nonlinear state space model (NSSM) PC-QDSOAs, effects SL-PCW dispersion relation as well homogeneous and inhomogeneous broadenings QDs are considered. To do so, SL on gain enhancement factor increase losses evaluated considering wavelength dependence modal confinement factor, group index dispersion, SL-enhanced absorption scattering SL-PCWs with QD active region. The saturation characteristics spectra PC-QDSOA investigated under different conditions including pump amplifier length. Simulation results show that can be used reduce transparency 20 even more compared conventional QDSOAs based ridge structures, enhance net region two six over broad range about 62 nm. We found power consumption PC-QDSOAs decreased 100, also length reduced five beyond, QDSOAs. paper useful many applications where low small size important.
