This paper proposes a fiber optic surface plasmon resonance (SPR) sensor based on the heterostructure of MoS2/WS2. Transition metal dichalcogenides (TMDCs) have been widely studied due to their high carrier mobility, excellent photoelectric properties and good biocompatibility. A heterostructure is constructed by two types of TMDCs (MoS2/WS2) and is used to improve the performance of the Ag layer coated fiber optic SPR sensor. The heterostructure film increases the integral of the electric field intensity on the surface of the sensor, thus improving the sensitivity of the sensor. The finite element analysis shows that the sensitivity of the sensor is as high as 3127.18 nm/RIU and the figure of merit is up to 70.04 RIU-1. The proposed sensor exhibits promising potential in the field of biochemical detection.
