If I use a 2D Grating Coupler component on my model and rotate it, am I to understand that it only applies to a 2D space or does it expand across the 3D surface?
I have a plane surface (xy) with a grating structure built up in the z direction in 2D. The alignment of the grating rotated to some angle between x and y. The structure is exposed to light polarized in the y direction, normal to z, to read the transmission through the structure in x polarization.
Is this clearly worded?
