A liquid level sensor based on a fiber Bragg grating (FBG) assisted by a section of multimode fiber core (MMFC) was demonstrated. Since the coupling coefficients between the MMFC and the single-mode fiber changes and FBG reflection modes keep still as surrounding liquid level varying, the liquid level can be determined by measuring the power of the FBG reflection core mode. Experimental results show...
•A novel refractive index sensor based on a FBG connected with MMFC is proposed and demonstrated. The SMF-MMFC-SMF fiber structure is sensitive to SRI, and its output power variation with SRI could modulate the core mode of FBG, which is proved in the theoretical analysis. This transforms the SRI information into the power variation of the FBG core mode to further realize the SRI detection.•The sensor...
