How could I simulate a photonics CLIPP (Contact Less Integrated Photonic Probes) circuit with simulink?

Hello,

I am fairly new to simulating circuits in Simulink. I would like to simulate a silicon photonics CLIPP (Contact Less Integrated Photonic Probes) circuit in Simulink. This would be in some sort of electrical domain I believe and I am not sure of which "domain" of tools to use. Simulink has several types of simulating components which do not interconnect to each other at all. From the library, I have tried the Simulink standard tool set, the RF toolset, and I have explored a few others.

In regard to the image below, I would be wanting to simulate somthing like this below where I can specify a voltage waveform, a dithering signal waveform and suppose the CLIPP current with a current waveform. I should be able to measure the output and so do not need an "integral contoller". Is there any way to do this without the use of resorting to the "electrical domain" and manually building all the mixers, filters, etc? A more abstracted domain would be nice

Even though a dedicated CLIPP model is not included in Simscape Electrical, an equivalent circuit can be implemented using existing blocks. A simple equivalent circuit is usually a capacitor (oxide layer) in series with a variable resistor (silicon conductivity changes with light) and possibly a parasitic capacitance.
