For a given mode in an electromagnetic wave propagating in a waveguide, such as an optical fiber, a slab dielectric waveguide, or an optical integrated circuit (OIC), the ratio of (a) the light velocity in vacuum to (b) the group velocity of the mode, given by the relation N = c /ν g where N is the group index, c is the light ...
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. Webindex. A material’s refractive index is a critical property for optical applications such as light-emitting diodes and optical fibers with applications that extend from communications and electronics to the automotive industry. Improved dielectric materials would not only allow for cheaper and more efficient devices but could also help in
