中文摘要： 基于光子晶体结构的布洛赫表面波具有传输损耗低以及显著的表面局域场增强的特点，因而被视为实现高灵敏度传感检测的关键技术发展方向。然而，由于光子晶体对传输光场的约束能力较差，这极大的制约了其在集成光子器件中的发展。本项目以实现兼具超低传输损耗、显著场增强效应以及光场束缚能力的传感器件结构为目的，提出基于光子晶体结构和金属狭缝结构相耦合的新型混合布洛赫等离激元结构。通过对混合结构耦合机制和模式特性等基础问题的理论分析和数值计算，结合标准加工工艺，实现混合模式传感器件的设计及样品制备，并对制备器件的光学传感特性进行测量。相关研究为设计、实现新型集成光子器件提供了重要的理论和技术基础。

英文摘要： The Bloch surface wave based on photonic crystal has the characteristics of low-loss and significant field enhancement at the surface, which has been regarded as one of the key solutions to realize highly-sensitive sensing. However, its development in integrated photonic devices is greatly restricted due to the poor confinement of light transport of photonic crystal. For the purpose of achieving a sensor with the features of ultra-low propagation loss, significant field enhancement and confinement, this program proposes a novel type of hybrid bloch plasmon polariton structure based on the coupling of photonic crystal and metal slot. Through theoretical analysis and numerical simulations of the fundamental issues including the hybridization mechanism and modal characteristics, combined with the consideration of fabrication technologies , design and fabrication of the sensor structure based on hybrid mode will be realized. Experiments will be then carried out to further investigate its properties of optical sensing. The above work in this program is expected to provide important theoretical and technical basis for realization of new integrated photonic devices.
