Paper Abstract

A single mode optical phase modulator utilizing a piezoelectric plastic jacket is studied theoretically. Due to the short wavelength at high frequency and the axial symmetry of the optical fiber, a radially dependent deformation is assumed. Computational results of the optical phase modulation reveal that the optimal performance may be achieved if the modulator is driven at its resonant frequencies. These resonances are caused by the thickness modes of the piezoelectric plastic jacket at lower frequencies and by the breathing modes of the glass fiber at higher frequencies. Experimental measurements (using a Mach-Zehnder interferometric configuration) up to 5 MHz on a 3 cm long sample show reasonable agreement with the theoretical predictions.
