Abstract

In this paper, we present and design a new type of tunable filter. The polymer with high electro-optic (EO) coefficient is fabricated as the outer layer of the long period fiber grating (LPG), since the resonant wavelength of LPG is extremely sensitive to the refractive index change outside the cladding, it is possible to achieve very fast speed broad tuning of wavelength by slightly tuning the refractive index of the surround area through the fast speed EO effect.
