Purpose This paper aims to propose and numerically analyze an etched weakly-coupled few-mode heterogeneous multi-core fiber sensor based on spatial-division multiplexed (SDM) Brillouin for simultaneous multiple-parameter measurement. Design/methodology/approach First, (WC-FMH-MCF) is designed improve the performance of sensing by optimizing structural parameters fiber. The core arrangement trench-assisted structure can significantly suppress inter-core crosstalk (XT). Then, fiber’s intramodal characteristics, such as frequency shift (BFS) gain spectrum (BGS), are studied. Finally, temperature, strain sample refractive index (SRI) in analyzed investigated, SBS. Findings numerical results show that minimum errors measurement SRI 0.12°C, 2.96 µe 9.2 × 10–2 RIU, respectively. Originality/value proposed WC-FMH-MCF provides a potential possibility better multi-parameter sensing.
