Abstract
We have investigated the influence of side-polished multimode fiber (SPMMF) core diameters D and residual radius R (the minimum distance between side-polished surface and the center of multimode fiber) on the sensitivity of a SPMMF based refractometer. We show that the residual radius has significant influence on the refractive index (RI) sensitivity but the core diameter does not. A refractometer with a lower SPMMF core diameter has a higher sensitivity. Experimental investigations achieved a maximum sensitivity of 42.23 dB/RIU (refractive index unit) for a refractive index range from 1.300 to 1.440 for a refractometer with a SPMMF core diameter of 50 μm.
