This paper reports a robust high refractive index (RI) sensor based on a multimode silica rod structure. The sensor was fabricated by splicing a segment of multimode silica rod between two single-mode fiber (SMF) leads. The measurement of high-RI is realized by monitoring the change of power spectru...
