Abstract

In this paper, we propose a numerical model for Four-Wave Mixing (FWM)
efficiency in quantum dot semiconductor optical amplifiers (QD-SOAs). Despite the
complexities of the equations governing the QD-SOAs, simple models with short
computational time are essential to analyze and design them. We present equations of
the QD-SOAs coherently and calculate FWM efficiency in the QD-SOA using the
pump/probe technique. In this model, the rate equations take into account the
occupation probabilities of each level instead of the carrier of densities. Moreover, the
transfer matrix based on the pump/probe measurement technique is solved in two
dimensions, space and time, using the Slice technique. The described model is
implemented in the MATLAB environment. The proposed model is simpler than similar
models and has a shorter computational time than them
