【Abstract】 A novel tunable nonlinear chirped fiber grating technology is simulated numerically by Matlab. The nonlinear chirped characteristics can be changed by the variation of the modulation period of the grating. The modulation period can be varied by imposing longitudinal strain, which is realized by the super magnetostriction film in the tunable magnetic field. 更多还原
