摘 要:A novel approach is proposed towards the design of fiber Bragg gratings with multi-channel right-angled triangular ***,a single-channel grating is synthesized utilizing an adaptive quantum particle swarm optimization with the piecewise constant mutated ***,the reflectivity spectrum with good linear edge for a short grating is ***,for its merits of easy fabrication,the superposition method is adopted to design multi-channel gratings with initial spectral ***,this distortion is optimized by the method in the first *** is shown that the design outcomes still retain the features of easy fabrication and short *** gratings would be useful as wavelength-interrogation devices with multiple physical parameters in optical sensor systems.
