Paper Abstract

Insertion loss characteristics of sampled fiber Bragg gratings were investigated theoretically and experimentally. The experiment results show that the LPG effect greatly influences the characteristics of insertion loss at the Bragg reflection wavelength when the LPG effect caused loss peak is coincide with the Bragg wavelength. This phenomenon will be obvious in the case of high duty-cycle of sampled fiber Bragg grating, for example, more than 1:9. Bending the SFBG will move the LPG-like loss peak and will then change the loss of SFBG reflection band. In experiment a reduction from 6.08dB to 2.56dB was obtained under a bend radius 17mm in a typical SFBG with duty-cycle 1:9.
