Effects of central dip in refractive index on propagation characteristics of W-type single-mode fibers
Effects of central dip in refractive index on the normalized cut-off frequency, normalized propagation constant, dispersion and power distribution of W-type single-mode fibers have been studied in detail.For typical W-type single-mode fibers, propagation characteristics will not show significant changes provided the width and depth of the central dip are less than 50%.
