In this paper, a new type of optical waveguide based on potassium tantalate niobate (KTN) electro-optic crystal is presented. The guiding property of the optical waveguide can be quickly (on the order of nanosecond) tuned and controlled by the applied external electric field, which can be useful for many applications such as broadband ultrafast optical modulators, variable optical attenuators, and dynamic gain equalizers.
本文提出了一种基于铌酸钾钽（KTN）电光晶体的新型光波导。光波导的导光特性可通过施加的外部电场快速（纳秒级）调谐和控制，这对许多应用，如宽带超快光调制器、可变光衰减器和动态增益均衡器等很有用。
