Deposition and characterization of thick Pb(Zr,Ti)O₃ films on optical fibers

In this work we report on the deposition of PZT thick film onto optical fibers and characterization of their microstructure, dielectric, and piezoelectric properties. PZT thick films were deposited onto standard single-mode optical communication fiber of a 0.125 mm diameter by dip-coating method. The final sintering temperature of the films was 600°C and the thickness was around 2 μm. Deposition procedure was developed for both bare fibers and for those with metallic coating (Pt). Bending vibrations of the fiber driven with the external electric field at different frequencies and under different applied voltages were studied.
