| 摘 要： | 采用迈克尔逊（Ｍｉｃｈｅｌｓｏｎ）光纤白光干涉系统，通过测量随着温度或应变改变而变化的光程，给出了单模光纤有效折射率的温度和应变相关特性。对于ＳＭＦ－２８型单模光纤，测得折射率温度系数和应变温度系数在波长为１３００ｎｍ处分别为０．７６２×１０－５／℃及－０．１３３２×１０－６／με；在波长１５５０ｎｍ处则为０．８１１×１０－５／℃及－０．１６４９×１０－６／με。并与几种不同光纤相应的数据进行了比较。

| Abstract: | By using white light fiber optic Michelson interferometer, the temperature and strain coefficients of fiber optic refractive index were determined via the measurements of optical path changing as a function of temperature or strain. The results shown that the temperature and strain coefficients of fiber optic refractive index were 0.762×10 -5 /℃ and -0.1332×10 -6 /με for 1300 nm wavelength and 0.811×10 -5 /℃ and -0.1649×10 -6 /με for 1550 nm for the type SMF 28 single mode communication optical fiber, respectively. The measured results were compared with published data. |
