用聚甲基丙烯酸甲酯代替金属薄膜作为耦合层，制备了高光致损伤阈值衰减全反射调制器，并通过计算棱镜波导结构的反射率，分析了器件的最佳工作条件。连续波激光和ns脉冲的光致损伤阈值分别高达~ 4 W/cm2和~ 0.2 MW/cm2。该器件为无线光通信的长距离传输和超短激光系统（如能量平衡、模式锁定或q开关）的应用提供了潜力。
A high light-induced damage threshold attenuated-total-reflection modulator is fabricated by replacing the metal film with poly(methyl methacrylate) as coupling layer, and the optimum conditions of the device are analyzed by calculating the reflectivity of a prism-waveguide configuration. The light-induced damage thresholds as high as ∼4 W/cm2and ∼0.2 MW/cm2for CW laser and ns pulses, respectively, are obtained. The device offers potentials in wireless optical communication for long distance transmission and applications in ultrashort laser systems such as energy balance, mode-locking or Q-switching.
