摘要
合成了一种新型有机-无机接枝改性聚甲基丙烯酸甲酯(PMMA)材料,基于材料良好的热稳定性以及光学特性,研制出一种工作于可见光650nm波段的全聚合物热光开关芯片。芯片设计采用倒脊型波导结构,可有效地实现红光信号的单模传输。在650nm波长下应用塑料光纤对热光开关进行测试,得到平均开关时间约为600μs,消光比为8.2dB,驱动功率为22.6mW。该器件可广泛用于高密度光集成系统,可见光通信及生化传感等领域。
An novel organic-inorganic grafting polymethyl methacrylate (PMMA) material is successfully synthesized. Based on the preferable thermal stability and optical properties, the all-polymer thermo-optic(TO) waveguide switch chip at 650 nm wavelength is designed and fabricated. The chip is designed as embedded waveguide with reversed ridge structure for single-mode propagation of the red signal light. The polymer optical fiber (POF) is used for coupling the 650nm visible light into the chip for testing. The Mach-Zehnder (M-Z) interferometer TO switch on-off time is about 600μs. The extinction ratio is about 8. 2 dB and the applied electric power as the switching power is about 22.6 mW. This device can be widely used in many fields such as high density optical integration system, visible light communication and biochemical sensing technology, etc.
