| Abstract: | The effect of optical loss in bent waveguide, change of fiber transverse section and index distribute on transmission of bent long-period fiber grating (LPFG) are discussed in this paper. The transmission of LPFG is analyzed by the means of equalizing the bent LPFG to a tilted quadric chirp LPFG. The approximate formula of period and chirp factor of effective grating is obtained. The transmission with different bent LPFG is numerically calculated by the transfer matrix method. |
