Abstract

Long period fiber grating is in-fiber device with the periodic structure and it is widely used in the area of optical fiber communication and sensing. With the more and more attention to the long period fiber grating in scientific research and application fields, the tunable long period fiber grating is developing as well. The paper mainly summarizes the design and achievement of tunable long period fiber gratings with electro-optic effect, magnetic-optic effect, thermo-optic effect and change of the surrounding in detail. And the LPFG in different tuning methods has different effects in tuning speed, tuning range, power consumption. With the efforts of many people, the tunable parameters can be improved and the application can be extended..
