Paper Abstract

Based on Mach-Zehnder interferometer and the Fiber Bragg Grating Sagnac Loop, a new structure of photo-fiber combfilter is designed which can obtain high reflectivity and big reverberation bandwidth. This filter has the advantage of low insertion loss and the equal intervals passband. The quantity and interval of passband can be changed through the length difference of optical fiber and without having to redesign and produce the fiber grating again. Within the range of the craft allows, the reverberation bandwidth of the filter amounts to 5 nm and the reflectivity nears to the 100% which can be widely applied in optical fiber sensors and optical fiber communication fields.
