报道了一种电光聚合物的筛选方法，重点是宽带器件的适用性。该方法是基于比较的信号从二次谐波产生（SHG）和漏电流（LTC）在极化。SHG和LTC的曲线图用于定义高EO活性-低电流极化窗口，该窗口对于具有相对较低光损耗的低驱动电压宽带器件至关重要。筛选过程用于选择EO聚合物芯，其导致具有1.3V的驱动电压和<8dB的插入损耗的40 Gbits scins宽带调制器。
A screening method is reported for electro-optic (EO) polymers with an emphasis on broadband device suitability. The method is based on comparing the signal from second harmonic generation (SHG) and the leak through current (LTC) during poling. Plots of the SHG and LTC are used to define high EO activity-low current poling windows that are critical for low driving voltage, broadband devices with relatively low optical loss. The screening procedure was used to select an EO polymer core that resulted in a 40Gbits∕s broadband modulator with a driving voltage of 1.3V and an insertion loss of <8dB.
