Abstract

Bragg grating-based optical systems are important for both telecommunications and sensor applications. Work to date on the simulation of such systems has concentrated upon using approximate methods such as the coupled mode theory (CMT). In this work, a combination of three numerical methods has ben used, all of which are rigorous and at the same time computationally very efficient. The new approach presented here incorporates the finite element, the least square boundary residual and the transfer matrix methods. The simulated results obtained show that the CMT is in general adequate for the characterization of Bragg grating devices in fiber, since the perturbed refractive index change is small. However, for Bragg grating devices in semiconductors, the CMT is shown to generate less accurate result. Simulated results obtained for various types of grating devices, such as uniform, chirped, apodized, phase-shifted, super- structures and sampled grating devices are presented.
