今天，新型可重构材料的创新，可以集成在硅片上并用于工程设备，是实现未来芯片级多功能系统的关键驱动因素，这些系统几乎影响生活的各个方面，从节能系统和高速互联网到小型消费设备。本项目为许多先进的光电子器件应用的硅片上动态可重构系统的片上架构提出了新的概念。这将通过使用新型可重构纳米复合材料来实现，该复合材料基于掺杂石墨烯的向列液晶。我们首次提出了将本课题开发的纳米复合材料渗透到硅光子平台中，并将其直接低功耗可控自组装成定义的微结构和微器件的光流技术。在本项目24个月内实现这一雄心勃勃的目标的方法是：(A)开发新型纳米复合材料集成在硅片上的平台；(B)展示了第一个集成在硅片微光子电路中的电/热驱动可重构器件，即具有在芯片平面上过滤、分裂和切换偏振光能力的有源超材料结构。

Today, innovation of novel reconfigurable materials, which can be integrated on Si chip and used for engineering devices, is the key driver for realization of future chip-scale multi-functional systems for applications impacting almost every aspect of life, from energy saving systems and high-speed internet to small consumer devices. This project proposes the novel concept for on-chip architecting of the dynamically reconfigurable systems on Si chip for many advanced optoelectronics device applications. This will be achieved using novel reconfigurable nanocomposites, based on nematic liquid crystals doped with graphene. For the first time, we propose the optofluidic technology for the infiltration of developed in this project nanocomposites into Si photonic platform and for their direct low-power controllable self-assembling into defined micro-structures and micro-devices. The approach to realize this ambitiouse aim in 24 motnhs of this project is (A) to develop novel nanocomosite material platform for integration on Si chip; (B) to demosntrate the first electrically/themrally driven reconfigurable device integrated into micro-photonic circuit on Si chip, i.e. an active metamaterial structure with an ability to filter, split, and switch polarized light in the plane of chip.
