Planar Waveguides with Continuous Dielectric Constant Variation, periodic focusing of the beam; most of the energy of the beam is concentrated around the central portion (where the refractive index is maximum) and hence the effect of irregularities (at the peripheries) on the beam is negligible.

Dielectric Clad Cylindrical Waveguides,ll subsequent analysis we will assume the cladding thickness to be infinite. It should be pointed out that even if the cladding material were absent the fiber would be able to guide the light beam, because air would then act as the second medium (i.e., .. = 1). However, it is always preferred to have a cladding because of the following reasons.
