I have not done that yet, but essentially from the research I've done you model the diode as a pulsed current source.

Where the current is I = Responsivity_curve * Light_intensity_in_watts/m^2 * Area of photodiode

I think the real answer is though unless you test it, it's all just fake numbers

I think the amount of testing I want to do is just see how much signal I can get out at different magnitudes of current

makes sense, cheers for the details! excited to see this thing taped out 🙂

Do you have plans for packaging, or just setting it up on a prober for testing?

@BreakingTaps / @Ethan Mahintorabi - Is this something you can simulate with TCAD or Emag simulation that gdsfactory has?

I'm not familiar enough with TCAD and what not. I don't know the answer

@BreakingTaps I'm still trying to figure out how to package it. I really don't have much equipment to test anything. I would ideally like to do chip on board, but without the glue blob

Will think on it! like 6 months ago I could have offered my shop services and a janky DIY wafer prober, but unfortunately I moved recently and am now shop-less 😢
