I am using a source diode which is propagating the light. The light rays pass through a laser rod from the side (cross sectionally) and the laser rod is in Z-plane(Longitudinally).
So if I want to assign TE polarisation to my source diode rays, is the following setup is right?
Thanks in advance

The orientation of the electric or magnetic field also depends on your chosen Polarization Reference Method. The X Axis Reference is set by default since many systems use the Z-Axis as the direction of propagation. However, in your case, the rays propagate along the X-Axis so using a Y- or Z- Axis Reference would be a better choice.
When you define Jx and Jy (Jones vector components), OpticStudio uses the following definitions to compute the appropriate E fields, where Jx is along S and Jy is along P:
Therefore, if we choose Y Axis Reference and we set Jx = 1 / Jy = 0, then you will have a TE polarization for each ray hitting the structure.
For more detailed information about defining polarization, please see the Help File: The Setup Tab > System Group (the Setup Tab) > System Explorer > Polarization (System Explorer) > Defining the Initial Polarization.
Thank you so much for your response. I want to clarify about one more thing.
If my ray travells on X-Y plane with an angle (for eg: 20° from the X - Axis and 70° from the Y-Axis), then can you please explain to me how can I assign the TE polarisation to the didode rays?
