# Real-coded genetic algorithm for Bragg grating parameter synthesis

@article{Cormier2001RealcodedGA, title={Real-coded genetic algorithm for Bragg grating parameter synthesis}, author={Gabriel Cormier and Roger Boudreau and Sylvain Th{\'e}riault}, journal={Journal of The Optical Society of America B-optical Physics}, year={2001}, volume={18}, pages={1771-1776} }

We propose to use a genetic algorithm to determine the physical parameters of Bragg gratings from their reflection spectra for both design purposes and fiber sensor applications. A real-coded genetic algorithm is used for inversion purposes, along with an F-matrix formalism for synthesis of uniform, chirped, and apodized gratings. An example of bandpass filter design is also studied. The method is easily applicable and shows promising results.
