SPICE equivalent circuit model of quantum-dot semiconductor optical amplifiers

摘要：

In this paper, we derive an equivalent circuit model for quantum dot semiconductor optical amplifier (QD-SOA) by employing rate equations for electronic transitions between QD’s levels and also the optical power propagation. The different parts of equivalent circuits interact together to represent the gain recovery process, saturation properties and chirp behaviour in both linear and nonlinear operation regimes of QD-SOA. The equivalent circuits are then used for SPICE simulation. We have shown that SPICE simulation results agree well with the full numerically calculated results.
