스텝인덱스 단일모드 광섬유의 최소분산 특성에 관한 연구

A Study on the Minimum Diepersion Characterlation of Step Index Single Mode Optial Pibers

In this paper mimimm desperaioms of atep index single mode sptical fibers manufzctrured by the phase madulatiem method.From them we find that the caloulated data agree closely with the resulte measured at the wavelength around 1.3 um and that a method to shift sere dispersion wavelength at the wavelenghth around 1.55 um is to control refractive index profile and relative refractive difference
