Paper Abstract

A piezoelectric polyvinylidene fluoride (PVF2) film with transparent indium tin oxide electrode metallization is placed directly in the path of a single mode fiber output to form an extrinsic optical interferometer. This device can be used concurrently with another extrinsic interferometer on a fiber directional coupler to generate a carrier phase modulation on which the signal phase shift is superimposed. Experimental results of the induced phase shifting coefficient are presented for two arrangements of the piezofilm differing in their boundary clamping conditions.
