In this letter, a new phase-shifted corrugated long-period fiber grating (PS-CLPFG) manufacture method is proposed based on burning the fiber coating and etching cladding method. We analyze the effect of phase amplitude, locations, and numbers on transmission spectrum. A proof-of-concept experiment is performed, and a good agreement of theoretical analysis and experiment results is obtained. In addition, a relative easier method to control band-pass and band-rejection characteristics is reached. Moreover, the obvious sidelobes in the passband of multiple-p PS-CLPFG can be effectively suppressed.
