摘要
采用马赫-曾德尔光波导干涉仪与锥形天线阵列,研制了基于铌酸锂(LiNbO_3)结构、可用于电力电场测量的大带宽电场传感器,并通过实验对传感器性能进行了测试。结果表明,该传感器在10kHz～18GHz的大带宽范围内,频响特性波动小于±10dB,最小可测电场强度达到0.4V/m,可测量场强达103V/m的纳秒脉冲电场。
A LiNbO3-based integrated optical sensor with Mach-Zehnder optical waveguide interferometer and tapered antenna array was designed and fabricated for electric field detection. Experimental results reveal that this sensor has a frequency response deviation less than ±10dB in the range of 10kHz^18GHz, and its minimum detectable electric field intensity reaches 0.4V/m. Moreover, a pulsed electric field with nanoseconds width and electric field intensity of 103V/m was realized.
