Abstract

As conventional silica fibers approach their performance limits in the face of exponentially growing demands for high data throughput in optical communication systems and constraints on power handling capability stemming from material limitations, several alternative technologies have been explored over the past decade. Despite the implementation of advanced multiplexing schemes and progress in digital signal processing capabilities, conventional fibers remain limited by their inherent physical constraints. In this advent, space division multiplexing, where the fiber cross-section comprises multiple simultaneous data channels, has been proposed as a potential solution to satisfy the bandwidth requirements of hyper-scale data centers, Artificial Intelligence infrastructures, and 5G/6G telecommunication systems. In this work, a number of multicore optical fibers are designed, fabricated, and investigated to analyze their crosstalk behavior under practical deployment conditions, such as bending. We employ advanced optical confinement techniques to achieve significant improvements in crosstalk performance relative to conventional step-index multicore fibers. Additionally, we investigate an emerging fiber-optic technology, namely anti-resonant fibers, in which light is guided by the principle of inhibited coupling. The design considerations and parameter optimization for such fibers, with both solid-core and hollow-core guidance, are presented. We demonstrate advanced nested hollow core fibers for UV wavelengths, and for multimode guidance. Finally, a novel multicore hollow core fiber is designed, fabricated, and characterized to demonstrate the potential of this technology.
