论文摘要
SAGNAC干涉仪的非近代性为参数估计提供了超高的灵敏度，并提供了广泛的应用，尤其是对于光纤传感。在这项工作中，我们研究了一种新型的非股展度，在光纤射击干涉仪中存在，其中考虑了依赖性损失。特别是，这种非股展与先前研究中所考虑的物理作用无关，该研究源自由连续锻炼诱导的几何阶段。因此，它具有突然的相变的独特现象，这可能为未来设计高精度光纤传感器的设计打开了新的方式。
The non-reciprocity of Sagnac interferometer provides ultra-high sensitivity for parameter estimation and offers a wide range of applications, especially for optical fiber sensing. In this work, we study a new type of non-reciprocity existed in optical fiber Sagnac interferometer where the polarization dependent loss is taken into consideration. In particular, this non-reciprocity is irrelevant to the physical effects that being considered in previous studies, which originates from the geometric phases induced by continuous-weak-measurement. In consequence, it has a unique phenomenon of sudden phase transition, which may open a new way for the future design of high precision optical fiber sensors.
