Hi,

I have made a Lumerical CHARGE model to model a laser that contains a single quantum well and uses lateral injection of carrier into the active region. I'm interested in the injection efficiency of the carriers into the quantum well. Here is a plot of the electron current density of my structure with the quantum well located in the middel. I would like to find Jn,top; Jn,btm and Jn,QW.

Hi You would need to use scripting to integrate current density over a desired region. The visualizer provides the matrices for coordinates (x, y, z). You can find the indices in these matrices that correspond to the region of interest (using if statements) and then use it to create a new current density matrix that only includes your desired region; afterwards you can proceed to use the integrate command.
Best regards
