Abstract

Fiber Bragg grating in single-multi-single mode fiber structure (FBG-in-SMS) is proposed to be used as a sensor. It could realize temperature and strain measurement simultaneously because of the different responses of the different parts of the FBG-in-SMS transmission spectrum. The temperature response is decided by the thermo-optic coefficient of the multimode fiber mainly, which is focused on especially in order to optimize its performance.
