Versatile Global Model for Semiconductor Optical Amplifier Design

We have developed a numerical model for semiconductor optical amplifier operation that takes into account carrier recombination and loss mechanisms, providing simulations of gain, noise figure and power saturation effects. The presented model, derived from existing models and specifically utilizing M.J. Connelly’s algorithm with appropriate modifications and customizations, is tailored to fit new multi-quantum wells slab-coupled waveguide semiconductor optical amplifier structures. A fiber-to-fiber peak gain of 15 dB with 7 dB noise figure and 17.5 dBm saturation output power are obtained in agreement with the measured values. These very first results are promising for developing a flexible model of highly engineered semiconductor optical amplifier designs.
