A systemic research on the birefringence of side-hole fiber is presented. The research results show that the birefringence of circular-core side-hole fiber relies mainly on stress birefringence, its fast axis is parallel to the link line of the two holes, and its intrinsic birefringence increases exponentially with the angle and ellipticity of side holes.
本论文的主要研究结果和创新在于: 1、对边孔光纤的双折射特性进行了系统研究,提出圆芯型边孔光纤以应力双折射为主,两边孔连线方向为其快轴方向,其双折射大小与边孔张角和边孔椭圆度成指数关系。
