[Invited Talk] Stress Distribution Analysis in Multi-Core Fibers

Abstract (in Japanese) (See Japanese page) 
(in English) Multi-core fibers (MCFs) offer a pathway to scale optical capacity beyond the limits of conventional single-mode fibers, but incorporating multiple cores introduces complex stress distributions that strongly affect intrinsic birefringence and polarization behavior. In this invited contribution, we review and expand upon our previously published work on stress distribution analyses of MCFs. By modeling representative structures, we examine how design parameters such as core count, pitch, refractive index profile, and spatial allocation influence birefringence and relate to reported polarization-mode dispersion performance. From these results, we outline key design principles for minimizing birefringence and mitigating polarization-related impairments.
