Paper Abstract

A novel all fiber-optic temperature sensor based on graphene film coated on a side polished fiber (SPF) was demonstrated. Significantly enhanced interaction between the propagating light and the graphene film can be achieved via strong evanescent light of the SPF. The experiments shows that the strong interaction results in temperature sensing with a dynamic optical power variation of 11.3dB in SPF. The novel temperature fiber sensor possesses a linear correlation coefficient of 99.4%, a sensitivity of 0.13dB/°C, a precision of better than 0.03°C. Furthermore, the graphene-based all fiber-optic temperature sensor is easy to fabricate, compatible with fiber-optic systems and possesses high potentiality in photonics applications such as all fiber-optic temperature sensing network.
