Application of Dispersion and Dispersion Slope Compensation Based on Optimization of Binary Phase-Sampled Fiber Bragg Gratings
优化二元相位取样光纤布喇格光栅及对色散和色散斜率补偿的应用

The binary phase-sampled fiber Bragg grating was optimized based on the particle swarm optimization method. Through the method, the dispersion and dispersion slope compensation technology were proposed by the binary phase-sampled fiber Bragg gratings. The bandwidth of each channel could be adjusted by the chirped period of the grating, and the total dispersion of each channel was dependent on the length of the seed grating. Finally the dispersion slope could be altered by adjusting the sampled function. So this technology is very attractive in design the multi-channel dispersion compensation devices for wavelength division multiplex system.
