摘要:

二维(2D)材料因其独特结构和优异特性,其片上集成赋予了集成器件新功能并提升了性能。氧化石墨烯(GO)凭借其性质调控的高灵活性和对各种集成平台的强兼容性,成为实现功能性混合集成器件的理想二维材料。在此,我们通过利用集成在芯片上的二维GO薄膜中的光热效应,展示了超越传统光子集成电路能力的新功能。这些功能包括全光控制与开关、光功率限制以及非互易光传输。二维层状GO薄膜在片上集成时,实现了对其厚度和尺寸的精确控制。得益于二维GO薄膜的宽带响应特性,这三种功能均具有极宽的工作带宽。通过将实验结果与理论拟合,我们还提取了由光热效应引起的材料特性变化,这揭示了关于二维GO薄膜的有趣见解。这些结果突显了二维GO薄膜在实现面向多种应用的功能性集成光子器件方面的多功能性。

英文摘要:

On-chip integration of two-dimensional (2D) materials with unique structures and distinctive properties endow integrated devices with new functionalities and improved performance. With a high flexibility in modifying its properties and a strong compatibility with various integrated platforms, graphene oxide (GO) becomes an attractive 2D material for implementing functional hybrid integrated devices. Here, we demonstrate novel functionalities that go beyond the capabilities of conventional photonic integrated circuits, by harnessing the photo-thermal effects in 2D GO films integrated onto them. These include all-optical control and switching, optical power limiting, and non-reciprocal light transmission. The 2D layered GO films are on-chip integrated with precise control of their thicknesses and sizes. Benefitting from the broadband response of 2D GO films, all the three functionalities feature a very wide operational bandwidth. By fitting the experimental results with theory, we also extract the changes in material properties induced by the photo-thermal effects, which reveal interesting insights about 2D GO films. These results highlight the versatility of 2D GO films in implementing functional integrated photonic devices for a range of applications.
