This paper proposes an all-fiber Mach-Zehnder interferometer (MZI) magnetic field sensor based on few mode fiber (FMF) and hollow core (HCF). The proposed SFHS (SMF-FMF-HCF-SMF) structure is achieved by fusion splicing FMF HCF between two single-mode fibers (SMFs), with the offset technique implemented SMF FMF. Through splicing, high-order modes are more easily excited when light propagates in FMF, while structural characteristics of reduce number modes, thus avoiding excessive interferences...
