In this study, a novel optical fiber sensor based on varying cladding diameters is developed to detect different tyramine concentrations. Single-mode fiber (SMF, 8.25/125 μm) and multimode fiber (MMF, 200/220 μm) are fused to form the SMF-MMF-SMF structure. The output signal is amplified by etching the fiber sensing region that can generate stronger evanescent fields. Multi-walled carbon nanotubes (MWCNTs) are used to enhance the sensing performance. The tyramine enzyme is used to functionalize the probe and realize the specificity of the probe for tyramine. The performance of the sensor is analyzed, and results show that the sensor has good selectivity. The results also show that the sensors based on different cladding diameters can be used as special sensors for measuring the concentration of tyramine.
