We propose that nanomaterials are 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 of phosphorus element 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 of 1.2-1.6 μm.As the wavelength varies from 1.20 μm to 1.60 μm,dispersion paramete...
