When the difference between core and cladding refractive index becomes very small (∆ ≪1), more light energy spreads into cladding. Thus light guiding capacity of the fiber becomes weaker making the structure weakly guided in nature.
For such weakly guided fibers it is observed that certain field components or modes …
