Model simulations of a reflective semiconductor optical amplifier

A reflective semiconductor optical amplifier is modeled using a rate equation for the inversion and an expression for the outgoing field in terms of the incoming field and the instantaneous inversion, for both the cases of linear and nonlinear gain, while assuming modulation speeds well below the round-trip frequency. Simulations are performed on the basis of these equations. Results for both the static and dynamic performance are presented and discussed.
