| Abstract | ||
| The purpose of this research is to design optical fibers which can be used for different of practical applications and study its characteristics :critical angle ,numerical aperture .normalized frequency ,number modes ,effective area .which are all function of wavelength .fixing the cladding material which has the smaller refractive index and varying the core material which has a larger refraction index ,three types of doped material was chosen : 16.9 m/o Na2O+32.5 m/o B2O3+50.6 m/o SiO2 ,7.9 m/o GeO2+92.1 m/o SiO2 ,1.0 m/o F+99.0 m/o SiO2and calculating the refractive index as function of wavelength using selimer equation and by a proper choice of the core and clad materials ,two type of optical fibers were designed .considering the communication windows ,the first fiber has core material of : 16.9 m/o Na2O+32.5 m/o B2O3+50.6 m/o SiO2 and a clad of 1.0 m/o F+99.0 m/o SiO2as receiving fiber clad to its large numerical aperture and the second fiber has a core material of 7.9 m/o GeO2+92.1 m/o SiO2and cladding material of 1.0 m/o F+99.0 m/o SiO2this can be used as transmitting fiber due to its small numerical aperture | ||
