Abstract
Rigorous formulation of a W-type fiber for its dispersion properties is presented. An LP mode has been studies extensively with respect to its attenuation properties when the frequency of operation is kept below cut-off. Due to rigorous dispersion equation numerical difficulties encountered in the computations, an approximate dispersion equation corresponding to weakly guided modes is solved. Numerical results corresponding to attenuation and propagation characteristics of the W-type fiber for radii and refractive index variations are presented. A computational subroutine for radial functions (Bessel, etc ) for complex argument has been used and proved to be useful in the legion of its validity. Previously published results for a step index fiber are used as a reference solution for the propagation properties of a W-type fiber when the radius of core and cladding is fixed.
