We propose that nanomaterials can be used for fibers. A novel nano-InP doped fiber has been fabricated by the method of modified chemical vapor deposition (MCVD). It has been measured that the doping concentration is 0.1%. The relationship between refractive index and the wavelength is obtained by fitting experimental data to Sellmeier equation. Dispersion of the fiber has been calculated in the wavelength range 1.2-1.6μm. As the wavelength varies from 1.2μm to 1.60μm, dispersion parameter D increases but is always negative. It has found that the dispersion of nano-InP doped fibers is strongly changed compared to standard single-mode fibers, due to the nano-InP dopant which lead to a higher refractive index difference.
