3.2 Show Grating

If you build a grating that is so complex you forgot how it looks like, or you have no confidence that the interface understand what you really want to build, you can check the grating on two levels.

On python level itself, by typing the name of the stack, e.g. for the 2D grating in example3, where "device" is the name of the stack type:

print device

To see the stack which the code uses, (so look at C++ level) type

print device.showgrating()

It's also possible to have an overview of the whole field and diffraction efficience.

print device.field() print device.diffr_eff()
