I am using the 2D grating coupler design given by Lumerical (https://kb.lumerical.com/en/pic_passive_grating_coupler_2d.html)
I want to orient the fiber given in the model from the XY plane to the XZ plane.
There is no ‘rotation’ option as given for the grating coupler structure.
Could someone please let me know how I can achieve this rotation?
Thanks!
