摘要
论述了单模光纤受到弯曲时应力双折射的产生。利用这种双折射效应制作了类似于经典晶体波片的光纤型波片。设计了测试光纤延迟角的实验系统并得到了１．５５μｍ在线光纤型波片。
in a bent single-mode fiber, lateral compressive stress under the conditions oflarge deformation induces a birefringence >β. This Permits us to conceive devices which are,for fiber optics, the analogue of fractional wave plates of classical optics. In the meantimewe designed a polarimeter to measure the bending- induced bireflingence and realized aquarter wave plate at = 1. 55 um with a two-turn optical fiber loop of 26 mm indiameter.
