Abstract :
A numerical model for calculation of the steady state gain properties for asymmetrical multiple quantum-well travelling wave semiconductor optical amplifiers (AMQW TW SOAs) has been newly developed. This model consists from the rate equation system for carriers in each quantum well and integrated gain model. Using this model the gain spectra and saturation characteristics for a 6 AQW TW SOA is calculated. The results show the AMQW SOA has a wide bandwidth of about 137 nm and a large saturation power of -8.8 dBm at 202 mA.
