ABSTRACT We design air cladding tellurite (TeO 2 ), bismuth oxide (Bi 2 O 3 ) based, and chalcogenide (As 2 S 3 ) nanofibers, and calculate the chromatic dispersions. For each mate rial, wavelength dependent propagation co nstants of the nanofiber are obtained from the exact solutions of the Maxwells equations, and from the propagation constants the chromatic dispersion is calculated. We tailor the dispersion to zero at the communication wavelength, 1.5 µm, by proper selection of the core diameter of the nanofiber for all the above materials. We further explain th e technique for flatteni ng the zero dispersion in telecommunication window, using glass instead of air, as the cladding of the nanofiber structure. Using the glass cladding has the advantage of easy handling, specially, for the communication purposes. Further, the glass cladding causes larger effective index difference between various modes of the nanofiber, thus reducing the mode coupling. We present the numerical results of the dispersion flattening technique by assuming the borosilicate glass cladding to the chalcogenide As
