We propose and demonstrate a novel earth's surface plasmon reverberance (SPR)-sensing move by using the significant mode beam based on a twin-core fiber (TCF). Although commonly in a fiber SPR sensor, a multimode fiber (MMF) has often been victimized to improve the coupling efficiency; for improving fiber SPR sensing element sensitivity, single-mode beam is optimal. We provide a novel know-how to employ the single (fundamental)-mode beam to SPR signification based on the TCF.
