In this paper we present a double clad optical fiber that consists of core, inner cladding and outer cladding. The refractive index of the core and the outer cladding are the same and the value of refractive index of the core is greater than the refractive index of inner cladding. The cutoff number Vc is calculated and plotted with respect to the ratio of the radius of inner cladding and the radius of the core. Finally the leakage losses are calculated considering both the bending effect and the non-bending effect. And a comparison is made between the double clad optical fiber and a single clad optical fiber.

 

Key words: Bessel’s function, cutoff value (Vc), cut off wavelength, loss co-efficient (2α)
