Abstract

Möbius optical cavities have attracted great interest for their unique topological properties. Here, the polarization and longitudinal modes of two types of Möbius fiber ring lasers are investigated. A theoretical model is established with Jones matrix to solve the polarization eigenmodes and longitudinal modes of a twisted polarization-maintaining fiber ring cavity. It is found that twisting the fiber axis causes polarization hybridization and a geometry-dependent phase, which induces a frequency shift to the longitudinal modes. The Möbius cases (180° and 90° splicing) are analyzed in detail, in which the 90° case leads to peculiar polarization and longitudinal mode properties. We believe the presented fiber ring laser provides a convenient platform to study lasers with a Möbius structure, and could enable further fiber laser applications.
