I want to be able to create GaInAsP alloys in lumerical CHARGE programmatically, particularly through the Python API. How can it be done?

[Guilin Sun]

You will need to know how to add such alloy using Lumerical script, then use Python to set it.

please post any further questions in the Photonics forum: /forum/forums/forum/discuss-simulation/photonics/

Indeed, but the problem is that I have not found a way top insert it even within lumerical scripting. Is it possible?

[Guilin Sun]

It seems there is no direct script to insert alloy. But you can set some alloy materials that you want to use, and use

addmaterialproperties

to the "materials" folder, and in the "model" you can assign material to a geometry. Using Lumapi to assign the "model".

However the api is not fully developed so please try and see if it works.

I understand. What I was trying to avoid was to have to search all the references to the 4 materials since you already have all the work done. What I was doing so far was to add the InP material and then alter the bandgap and mobilities, but there are many other quantities. It would be very useful to be able to use your database that fluently. This is useful when one wants to scan various concentrations of the alloys.

You can use "set" to modify most material properties: https://optics.ansys.com/hc/en-us/articles/360034919213-Creating-and-modifying-electrical-materials-from-a-script
