Optical-fiber phase modulator with enhanced modulation efficiency.
A novel piezoelectrically driven optical-fiber phase modulator is described. The modulator has low thermal drift and minimum polarization modulation and is immune to variations in the characteristics of the piezoelectric transducer. The theoretical model of the modulator accurately predicts the experimental performance, showing a phase-modulation enhancement over a wraparound fiber modulator at resonance.
