摘要
Dispersive fibers whose refractive index differences change greatly with wavelength are fabricated from optical glasses with different index dispersions. The fibers have several guided modes, and are changed into single-mode fibers by annealing under suitable conditions. The number of guided modes is investigated by measuring the bending loss and the mode lines of annealed dispersive fibers. The annealed single-mode fibers support only the fundamental mode ol er broad spectral ranges and no second guided mode at any wavelength.
