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). WebThe total electromagnetic fields of an optical waveguide can be expressed as the sum of two components. One component, expressible as a summation over bound modes, describes the spatial steady state, where energy is guided indefinitely along a nonabsorbing waveguide. The second component is the radiation field, which describes the spatial ...
