Frequency- and time-domain simulations of semiconductor optical amplifiers using equivalent circuit modeling

Abstract. We propose an equivalent circuit modeling for a chip-on-carrier and for two encapsulated semiconductor optical amplifiers (SOAs). The models include main parasitic leaks and were used in reflection and transmission simulations, showing good agreement with experimental data. The model for each SOA is validated, comparing the simulated results with experimental data from SOAs operating as high-speed electro-optical switches, reaching rise times below 200 ps.
