A simple and novel way of attenuation is presented to investigate the feasibility of affecting the coupling cylindrical waveguides. Piezoelectric polymers such as PVDF (Poly Vinyledene Fluoride) are very attractive for many applications as they exhibit good piezoelectric and pyroelectric responses and low acoustic impedance. Moreover, their properties can be tailored according to the desired requirements. PVDF actuators are proposed because of their low cost and simple process of fabrication. In this paper, cylindrical waveguides are actuated by means of a piezoelectric actuator using PVDF (Poly Vinylidene Fluoride) material. The presented results include the design and analysis of a new cylindrical waveguide based attenuator with PVDF actuation. The presented results include the influence of PVDF (Poly Vinylidene Fluoride) actuation on the optical coupling efficiency. The paper also includes the parametric study on the variation of the geometry of PVDF film with respect to the coupling efficiency. The results also include the variation of deflection and power loss through cylindrical waveguides for various applied voltages. The paper demonstrates a simple and novel application of PVDF film for optical microsystem.
