摘要：
A liquid level sensor based on single leaky mode attenuation in a single-mode-multimode-single-mode (SMS) fiber structure is proposed and demonstrated, which aims at the liquid whose refractive index is higher than that of the silica fiber. Its operating principle is investigated theoretically by using the mode expansion method, and a monotonic and linear sensing response is obtained. Experiments are then carried out to verify the theoretical analysis.
