I have a question regarding the use a of slab waveguide.
A light source ( LED ) is coupled into a slab waveguide, after a few
millimeters of propagation in the guide, I m wondering how to get beam
parameters at the output of the guide when it's free space propagation
Is there a link between input and output beam divergence or does it
only depends on the waveguide geometry ?
Thank you for your answers,
