In the optical biosensor technology, the demand for higher sensitivity and larger quality factor has become a common understanding in the scientific community, in which the hyperbolic metamaterial biosensor has attracted much attention because of its novel working principle and excellent performance. This project introduces the slow-light effect into biosensor technology based on metal nanorod hyperbolic metamaterials, and proposes a new mechanism of slow-light effect which can significantly improve the sensing sensitivity. This project also presents the grating coupler composed of the periodic structure of the plasmon polaritonic crystal type combined with the metal nanorod hyperbolic metamaterial waveguide to excite the TM guided mode with slow light effect in the critical condition of the metamaterial waveguide, in which the High quality factor integrated biochip can be obtained. In this project, we study the dispersion properties of metal nanorod hyperbolic metamaterial waveguide, the physical mechanism of slow light effect. The effects of critical conditions and loss factors on the slow-light effect are also investigated. An integrated nano biosensor sample with slow light enhancement effect is explored and fabricated by using the semiconductor process. The implementation of this project will show a new direction for the development of cross-fusion of metamaterials, micro-nano integration and optical biosensor. At the same time, the slow light effect of hyperbolic metamaterials also has a bright future in optical non-linear devices, optical buffers, optical routers and so on.
