Phenomenon used in optical fibres
WebA graded-index or gradient-index fiber is an optical fiber whose core has a refractive index that decreases with increasing radial distance from the optical axis of the fiber.. Because parts of the core closer to the fiber axis have a higher refractive index than the parts near the cladding, light rays follow sinusoidal paths down the fiber. The most common refractive … WebMaterial dispersion is a delay-time dispersion caused by the fact that the refractive index of the glass material changes in accordance with the change of the signal frequency (or wavelength). Figure 3.10 shows the dependence of refractive indices of the core and cladding on the frequency for an optical fiber with relative refractive-index difference ∆ = 0 …
