“…HE intrinsic stress-induced birefringence (SIB) in polarization-maintaining optical fibers (PMFs) is one of the most crucial characteristics in several applications, e.g. fiber optic sensing [1], loop mirror [2], current transformers [3], acoustic-optic modulators [4] and gyroscopes [5]. The SIB in PMFs originates from the stress difference between two principal axes, produced by embedded stress-applying parts (SAPs) via the difference between the coefficient of thermal expansion (CTE) in SAPs and that in the fiber cladding [6].…”
An analytical model for estimating the stress -induced birefringence in true Panda-type polarization -maintaining fibers with imperfect geometry has been developed in this letter. The developed model is simpler and more accurate compared to conventional sophisticated and asymptotic formulas in reported works. Our model provides a clear and simple solution to demonstrate the periodic dependence of the birefringence on the misalignment angle between the two stress-applying parts, and the monotonic dependence on the geometric parameters of stress-applying parts. Our work also reveals the important role of the misalignment angle between the two stress-applying parts in practical Panda-type fibers.

“…The stress-induced birefringence (SIB) which is intrinsic in PMFs is usually very high [6], [7], which enables the fiber to be immune to external perturbations [8], [9]. The SIB critically affects the polarization-maintaining capability of PMFs and hence the performance of systems using PMFs [10], [11]. Generally, the better performance comes from the higher SIB of the fiber, which has already become one of the main targets in the design and fabrication of PMFs [12].…”

“…One is the intrinsic perturbations such as polarization cross-couplings in fibers [7,8] and splicing misalignments between fibers [9,10]. The other is the external perturbations from surrounding environments such as thermal fields [11][12][13], magnetic fields [14][15][16], and thermal stress fields [17][18][19]. Another new type of error source identified recently is the topology of the optical circuit formed in the coiled fiber [20][21][22][23][24].…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
