WebDispersion is the dependence of light’s phase velocity or phase delay as it transmits through an optical medium on another parameter, such as optical frequency, or wavelength. Several different types of dispersion can occur inside an optic’s substrate: chromatic ( Figure 1 ), intermodal, and polarization mode dispersion. 1. Weboptical fiber waveguide. In single-mode fiber, the vast majority of the light signal travels in the core while a small amount of light travels outside the core/clad interface (or in the cladding). In multimode fiber, light encounters the varying refractive index values associated with the graded refractive index profile design.
