Overcoming Dispersion Limitations: A Review of Non-Zero Dispersion-Shifted Fiber Designs for Orbital Angular Momentum Mode
Orbital angular momentum (OAM) modes, characterized by their helical phase front and annular intensity profile, manifest the spatial distribution information of the electromagnetic field. In fiber–optic communication, implementing OAM modes offers an additional spatial multiplexing dimension, enabling significant capacity increases for communication system. To effectively utilize OAM modes as independent and stable transmission channels, various ring-core fibers are proposed and fabricated to match the annular intensity distribution of these modes. Among these designs, a series of non-zero dispersion-shifted ring-core fibers (NZDSRF) emerges as a promising approach for dispersion management in OAM-based transmission. By carefully engineering the dispersion characteristics of the fiber, NZDSRFs can minimize signal pulse broadening, making them more suitable for long-distance OAM multiplexing systems. This summary presents an overview of various NZDSRF designs and compares their capabilities in dispersion management of OAM modes.
期刊介绍：
Annalen der Physik (AdP) is one of the world''s most renowned physics journals with an over 225 years'' tradition of excellence. Based on the fame of seminal papers by Einstein, Planck and many others, the journal is now tuned towards today''s most exciting findings including the annual Nobel Lectures. AdP comprises all areas of physics, with particular emphasis on important, significant and highly relevant results. Topics range from fundamental research to forefront applications including dynamic and interdisciplinary fields. The journal covers theory, simulation and experiment, e.g., but not exclusively, in condensed matter, quantum physics, photonics, materials physics, high energy, gravitation and astrophysics. It welcomes Rapid Research Letters, Original Papers, Review and Feature Articles.
