We design a high dynamic range electric field sensor based on domain inverted electro-optic (E-O) polymer Y-fed directional coupler for electromagnetic wave detection. This electrode-less, all optical, wideband electrical field sensor is fabricated using standard processing for E-O polymer photonic devices. Experimental results demonstrate effective detection of electric field from 16.7V/m to 750KV/m at a frequency of 1GHz, and spurious free measurement range of 70dB.
我们基于畴反转电光（E-O）聚合物Y分支定向耦合器设计了一种用于电磁波检测的高动态范围电场传感器。这种无电极、全光学、宽带电场传感器是采用E-O聚合物光子器件的标准工艺制造的。实验结果表明，在1GHz频率下能够有效检测16.7V/m至750KV/m的电场，无杂散测量范围为70dB。
