WebAn optical wave guide is a structure that "guides" a light wave by constraining it to travel along a certain desired path. If the transverse dimensions of the guide are much larger than the wavelength of the guided light, then we can explain how the optical waveguide works using geometrical optics and total internal reflection (TIR).

Webever, modes of guides with transversely nonuniform material parameters are generally hybrid rather than TE, TM, or TEM.
