Abstract

Freeform TIR prism combiners are at the interface between free-space and waveguide combiners. When the number of TIR bounces increases, one might refer to them as waveguide combiners, which are the topic of this chapter. Waveguide combiners are based on TIR propagation of the entire field in an optical guide, essentially acting as a transparent periscope with a single entrance pupil and often many exit pupils.
