Abstract :
A polyvinylidene fluoride (PVF 2) phase shifter is characterized in terms of amplitude response uniformity, frequency response uniformity, and ultimate sensitivity to electric field. Phase-drift compensation with this PVF 2 device is demonstrated in a Mach-Zehnder fiber interferometer. The compensator can be operated at the pi/2-phase mode for maximum sensitivity in detection applications, or the pi-phase mode for maximum frequency mixing efficiency.
