Abstract :
The influence of grating structure on magnetic field measurements based on differential group delay of fiber gratings is presented. Theoretical simulations are realized using the coupled mode theory. The experiments show good agreement with simulations. The compares show that the non-uniform Bragg gratings can improve the sensitivity of sensor system.
