Abstract
There is an upward trend in applying the spatial division multiplexing (SDM) technologies from the telecom field towards multi-functional optical sensing applications attributable to enhanced spatial sensitivity and multi-parameter discriminative proficiency. In addition to our preliminary experimental demonstrations, in this paper we analytically evaluated the performance of few-mode Brillouin sensors via diverse refractive index profiles and dopant material compositions. Our results show five to ten folder improvements on the measurement accuracy associated with the intermodal differential Brillouin frequency shifts, which would be of great importance for sensing in sophisticated target environments. This work pave the way for next-generation mode division multiplexed sensing system design and corresponding high nonlinearity specialty fiber fabrication for structure health monitoring as well as oil and gas pipeline monitoring.
