Abstract :
We have developed a technique to calculate the amplitude of the electric field of a lightwave propagating through a fiber Bragg grating (FBG). The technique is based on a transfer matrix method developed for electric field calculations in multilayer thin films. The internal electric field distribution of FBG structures having uniform, tapered chirped, and phase-shifted index modulations has been calculated. Two-dimensional plots of the average internal power versus the distance along the grating axis and light frequency are presented.
