Abstract

The core layer of an optical waveguide device was fabricated by doping the photosensitive chromophore spiropyran derivative SP-Br into poly(methyl methacrylate) (PMMA). The design of the core layer allows us to precisely control the optical property of the waveguide using the photoisomerization process of SP-Br. Under UV excitation, the controllable conversion between SP-Br and the merocyanine isomer MC-Br allows dynamic and continuous changes in the refractive index, thus enabling the function of repeated writing and erasing of optical paths in the optical waveguide device. The ability to dynamically adjust the refractive index provides unprecedented flexibility in the design and fabrication of an optical waveguide device.

基于光敏发色团光异构特性的可重写聚合物光波导芯片

将光敏发色团螺旋吡喃衍生物SP-Br掺杂到聚甲基丙烯酸甲酯（PMMA）中制备光波导器件的核心层。核心层的设计使我们能够利用SP-Br的光异构化过程精确地控制波导的光学特性。在UV激发下，SP-Br与merocyanine异构体MC-Br之间的可控转换使得折射率动态连续变化，从而实现光波导器件中光路的重复写入和擦除功能。动态调整折射率的能力为光波导器件的设计和制造提供了前所未有的灵活性。
