Abstract

Designing and modeling a waveguide combiner is very different from designing and modeling a free-space optical combiner, as discussed in Chapters 9, 11, and 12. As conventional ray tracing in standard optical CAD tools such as Zemax^TM, CodeV^TM, Fred^TM, or TracePro^TM is sufficient to design effective free-space and even TIR prism combiners, a hybrid ray-trace/rigorous electro-magnetic diffraction mode is usually necessary to design waveguide combiners, especially when using diffractive or holographic couplers.
