A fiber has a core made from 86.5%SiO2-13.5%GeO, with a diameter of 8 µm and a refractive index of 1.468 and cladding with a refractive index of 1.464. Both refractive indices are for light with A= 1300 nm where the fiber is operated using a laser source with a half maximum width of 2 nm. (a) Calculate the V-number for the fiber. Is this a single mode fiber? (b) Calculate the wavelength below which the fiber becomes multimode. (c) Calculate the numerical aperture. (d) Calculate the maximum acceptance angle.
