摘要: In this paper, we present a theory of an optical fiber acoustooptic phase modulator using piezoelectric zinc oxide (ZnO) coating. The effects changing device parameters in the resonator are investigated for transducer design. These results entirely different from those well-known; planar structure since every part plays important role structure. Optical modulation frequency region up to 1 GHz is also demonstrated. Multiple sharp resonance peaks with maximum shift 0.7 radians observed.
