A cylindrical PZT around which some length of a fiber is wound is demonstrated as a component of optical phase shifter and modulator in a single-mode fiber interferometer. Its sensitivity under the operation of DC input mode is 0.18 π rad/V/meter in phase change at the optical wavelength of 6328 . Some characteristics of amplitude response linearity and frequency response uniformity for the AC drive voltage applied to the PZT cylinder are also discussed.
