For dielectric waveguides of arbitrary profile with step-index and gradient-index, the universal expressions of eigen mode expansions of dyadic Green's functions for dielectric waveguides have been found by using the approach of operator theory. It is shown that the expression of electric-type dyadic Green's function is the sum of an eigen-mode expansion containing nine dyadic components and a singular term. From these expressions the dyadic Green's function for a dielectric waveguide can be obtained if...

The subject of gradient-index optical is subdivided into two majorapplications. The first is gradient-index elements used for communications. The se-cond major application is for imaging purposes. Gradient-index fiber is a new com-ponent of gradient-index optics. The surfaces of constant refractive index for cy-lindrical gradient-index fiber will be cylinders concentric with the axis, after be-ing pulled into a tapered form, the surfaces of constant refractive index will becones concentric with the axis and having a common apex. Tapered gradient-indexfiber lens is a novel optical plane lens. In this paper, starting from the paraxialmeridional ray path equation, object-image relationships are found and used to de-termine the equivalent focal length and the principal planes of tapered gradient-indexfiber lens. The position of principal planes and focal point for the entry and exitof the tapered gradient-index fiber lens could have been obtained directiy by invo-king the symmetry condition and replacing r_1 or r_2. These equations reduce to theknown formulas when k=0, r_1=r_2 (that is, for a cylindrical gradient-index fiberlens). The image of tapered gradient-index fiber lens (r_1=0.54mm, r_2=0.27mm,z_0=3mm; r_1=0.54mm, r_2=0.38mm, z_0=2.5mm) is shown by photographs.
