英文摘要： With the advanced research on body area network technology, wearable and implantable monitoring devices for human health have emerged. As the core component for future sensor networks, integrated micro-and nano-sensors with ultra-compact footprints and high sensitivity could meet the requirements of accurately monitoring human health information in real-time. Recently, novel photonic crystal micro- and nano-sensors with high detection performance have attracted great attention due to high potential in system performance and advantages in device integration. The goal of this project is to realize high-performance integrated micro- and nano-sensors that combines optical fibers with two-dimensional photonic crystals. By calculating the band structure and the guided-mode characteristic of photonic crystals, coupled resonant phenomena between the guided-modes within light-cone and external radiation modes in the vertical direction of photonic crystals will be analyzed. Light-controlling mechanisms and sensing performance of the aforementioned optical sensing system will be studied. Then, the structural model of novel sensors based on fiber-integrated photonic crystals will be proposed and designed. By means of theoretical simulation and experimental test, the proposed novel sensor performance will be analyzed, evaluated and verified, which could provide a powerful reference for its application prospects and potential performance in the future sensor network.
