In this Letter, we reported anomalous electro-optic potassium tantalate niobate (KTN) devices, in which both electrons and holes were injected into the KTN crystal via ultraviolet (UV) illumination-assisted charge injection. This could not only significantly enhance the performance of electro-optic devices (e.g., a 270% increase in the deflection angle in terms of the KTN deflector) but also enable the new bi-directional scanning capability. The results in this work would be very useful for a variety of devices and applications, such as electro-optic based vari-focal lenses.

带有紫外线辅助电子和空穴注入的异常双向扫描电光KTN设备

在这封信中，我们报道了异常的电光钽酸钾铌酸钾（KTN）器件，其中电子和空穴都通过紫外线（UV）照明辅助的电荷注入注入到KTN晶体中。这不仅可以显着提高电光设备的性能（例如，相对于KTN偏转器，偏转角增加270％），还可以实现新的双向扫描功能。这项工作的结果对于各种设备和应用（例如基于电光的变焦镜头）将非常有用。
