Abstract
Orbital angular momentum (OAM) modes, an orthogonal complete basis for electromagnetic field distribution in optical fibers, offer a promising technology for independent spatial-domain transmission. Various ring fibers have emerged as leading candidates for supporting and manipulating OAM modes. Among these designs, benefitting from the high index contrast, the air-core ring fiber enables a larger number of supported OAM modes and wider effective refraction index separations between OAM modes. In addition, the air-core structure also provides flexibility for dispersion engineering. This paper presents an overview of air-core ring fibers, highlighting their diverse capabilities and potential applications in OAM-based optical communication systems and beyond.
期刊介绍:
Optics Communications invites original and timely contributions containing new results in various fields of optics and photonics. The journal considers theoretical and experimental research in areas ranging from the fundamental properties of light to technological applications. Topics covered include classical and quantum optics, optical physics and light-matter interactions, lasers, imaging, guided-wave optics and optical information processing. Manuscripts should offer clear evidence of novelty and significance. Papers concentrating on mathematical and computational issues, with limited connection to optics, are not suitable for publication in the Journal. Similarly, small technical advances, or papers concerned only with engineering applications or issues of materials science fall outside the journal scope.
