| Abstract: | In this paper,temperature characteristics of quarter-waveplate are analyzed theoretically.With
temperature changes,the change of phase retarder of quarter-waveplates made of panda fiber,and
geometrical birefringent fiber are discussed respectively.Quarter-waveplates made of geometrical
birefringent fiber is more insensitive.And two types of quarter-waveplates made in our laboratory are measured too.The results show that,between -40 ℃ and 60 ℃,the quarter-waveplate made of geometrical birefringence fiber has better temperature characteristics than that made of panda fiber. |

| Keywords: | fiber optical current sensor fiber quarter-waveplate temperature characteristic |
