Synthesis of Long period Fiber Gratings with given Magnitude and Phase Profiles

摘要

We propose a new method for synthesizing long peirod fiber gratings. The proposed method which employs the simulated annealing and steepest descent algorithms is capable of controlling the phase as well as the magnitude characteristics. To verify the validity of the proposed method, we have synthesized three simple structures; a single long period fiber gratings structure and two piecewise-uniform long period fiber gratings structures.
