All fiber temperature sensor based on TMD alloy coated tapered fiber
All fiber temperature sensor based on MoWS2-rGO coated tapered fiber is demonstrated. The large evanescent field of tapered fiber allows MoWS2-rGO coated tapered fiber to absorb the surrounding heat and changes the refractive index of MoWS2-rGO coated tapered fiber. The refractive index change is du...

| Summary: | All fiber temperature sensor based on MoWS2-rGO coated tapered fiber is demonstrated. The large evanescent field of tapered fiber allows MoWS2-rGO coated tapered fiber to absorb the surrounding heat and changes the refractive index of MoWS2-rGO coated tapered fiber. The refractive index change is due to thermo-optic effect. When there is a change of surrounding temperature, the refractive index of the coated tapered fiber changes and this subsequently alters the incident light polarization. The sensitivity of the proposed temperature sensor is measured at 0.63 degrees/degrees C. This is the first demonstration of using MoWS2-rGO tapered fiber as temperature sensor. |
