I would like to use the TWLM element in INTERCONNECT to simulate a Semiconductor Optical Amplifier. Ideally, I would like to be able to simulate the attached circuit. However, I’m not sure how to use the TWLM as an SOA. I know it can be done as I’ve seen other support posts where it has been answered that it is possible, but are there any examples I can look at to see how it is done? Thank you.
Thank you for the question. Basically, using the TWLM element for an SOA is the same as using it for a laser, but you set the facet reflectivities to zero. Here is an example that uses the data and settings from the Multi-quantum well (MQW) edge emitting laser example to create an SOA element: SOA_example.zip (1.8 MB)
I hope this helps. Let me know if you have any questions.
Thank you so much for the example! I had inferred that I needed to set the facet reflectivities to zero and had tried that before, but it hadn’t worked for me. That example is very helpful to see that I was on the right track!
Still, do you think that INTERCONNECT could adequately simulate the attached circuit? I can’t seem to figure out how to make a circuit of SOAs in series like the one in the picture.
Unfortunately I don’t think the TWLM element could be used in a circuit like this. The electrical input for the TWLM is the bias current and the electrical output is the carrier density, so I don’t think you could combine them in a series circuit like this.
Please let me know if I can help you with anything else.
