SOA Device Simulation

I am looking to simulate an SOA device with a PIN structure. I have tried using the device given here but I need to be able to simulate the reverse bias characteristics of the device and cannot seem to get a reverse bias simulation to converge. I would also like to be able to export this data to FDTD Solutions in order to simulate the optical effects of the device.

Does anyone have suggestions on how I might be able to do this?
