Coating process of nanocomposite on fiber. Fiber is drawn downward from a die containing nanoparticle-polymer solution. Solution drawn out with the fiber forms a thin film of nanocomposite after evaporation of solvent. Coating thickness is controlled by solution concentration and drawing rate.
(a) UV-visible spectrum of neat P(VDF-TrFE-CFE) terpolymer and nanocomposite with ZnS, both thick. (b) Refractive index of the nanocomposite measured by ellipsometer and calculated from effective medium theory. (c) Electrical field induced IR transmission spectrum shift of a silver coated nanocomposite film with ZnS. Film thickness: . Curves have been offset for easier comparison. is marked to guide the fringe shift.
Schematic of an EO tunable long-period grating.
Spectra of (a) LPG immersed in different index matching fluids. Fiber radius: ; (b) LPG coated with neat terpolymer under different electric fields. Fiber radius: ; (c) LPG coated with nanocomposite containing ZnS under different electric fields. (d) Improved LPG immersed in different index matching fluids. Fiber core radius: , core index: 1.4491, cladding index: 1.4441, grating period , and grating length: . Gratings in (a) and (c) have the same parameters.
