    Very large electro-optic effect has been observed in relaxor ferroelectric poly(vinylidene fluoride-trifluoroethylene-chlorofluoroethylene) ( P(VDF-TrFE-CFE) ) terpolymer. By adding small amount of zinc sulfide (ZnS) nanoparticles, the refractive index of the nanocomposites can be tuned between about 1.4 and 1.5 while retaining large electro-optic effect and high transparency. Tunable long-period fiber gratings have been fabricated with the nanocomposite as the second cladding, and over 50nm of resonant wavelength shift has been achieved under a change of electric field of 30V/μm, which is much larger than other reported E-O tuning ranges. This corresponds to a pure refractive index change of the nanocomposite of An/n ∼ 0.4%.
