چکیده:
To compensate for the decreasing carrier density inthe far side of quantum-dot semiconductor optical amplifiers(QD-SOAs), which directly compromises the optical gain,multi-electrode approach for these devices is introduced. In ourstudy two and three-electrode QD-SOA are studied and tried toestablish a base for comparison between these multi-electrodetechniques and constant form of injected current. The opticalgain of QD-SOA is improved by nearly 10% throughdiscretizing the optimum non-uniform current and thenapplying it to multi-electrode structure. For doing so, the rateequation model is employed and solved through finite differencemethod and MATLAB ODE.
