In this work, thermo-optic (TO) waveguide switches are designed and fabricated based on the bottom-metal-printed technique. Low-loss fluorinated polycarbonate (AF-Z-PC MA) and polymethyl methacrylate (PMMA) are used as core and cladding materials, respectively. The thermal stability and optical absorption characteristics of AF-Z-PC MA are analyzed. The optical and thermal field distributions of the TO switch are simulated. The insertion loss and extinction ratio of the device are found to be 4.5 dB and 19.8 dB, respectively, at a wavelength of 1550 nm. The on-off time of the switching chip is 80 µs. The electrical power consumption is approximately 8.8 mW. The proposed low-loss fluorinated polymer TO waveguide switch realized by bottom-metal-printed fabrication technology is suitable for large-scale integrated photonic circuit systems.

基于低损耗氟化聚碳酸酯材料的底部金属印刷热光波导开关。

在这项工作中，基于底部金属印刷技术来设计和制造热光（TO）波导开关。低损耗氟化聚碳酸酯（AF-Z-PC MA）和聚甲基丙烯酸甲酯（PMMA）分别用作芯和包层材料。分析了AF-Z-PC MA的热稳定性和光吸收特性。模拟了TO开关的光场和热场分布。发现该器件的插入损耗和消光比在1550 nm波长下分别为4.5 dB和19.8 dB。开关芯片的通断时间为80 µs。功耗约为8.8 mW。通过底部金属印刷制造技术实现的拟议的低损耗氟化聚合物TO波导开关适用于大规模集成光子电路系统。
