*Abstract:

Nano-optical resonant structures can enhance the interaction between light and matter in the near field by tuning the distribution of local electromagnetic fields at subwavelength scales. Therefore, these structures have demonstrated many novel phenomena in various fields, such as optical trapping, optical sensing, micro/nano lasers, and nonlinear optics. When the material absorption cannot be neglected, the locally enhanced electric field induced by resonance enables us to manipulate the temperature field distribution in micro/nano systems and thereby control the fluid flow in microfluidic channels. In this presentation, I will briefly introduce some achievements of our research group in the manipulation and trapping of nanoparticles, optical sensing, and micro/nano light sources by designing plasmonic and dielectric nano-optical structures.

*Profile：

Sen Yang is a fifth-year PhD candidate currently studying at Vanderbilt University in the United States. He received his bachelor's and master's degrees from Harbin Institute of Technology in China in 2015 and 2017, respectively. His PhD research focuses on developing high-Q resonant dielectric nanostructures, such as photonic crystals and bound states in the continuum, for efficient nanoparticle trapping and manipulation. Yang's research is multidisciplinary and combines the study of light-matter interactions at the near-field with hydrodynamic processes in microfluidics. The applications of his research cover a range of fields, including self-assembly of nanoparticles, enhanced spectroscopy, enhanced light emission, and high-sensitivity detection of nanoscale biological objects. Recently, Yang's interests have also expanded to include thermal emission at mid-IR based on high-Q resonances.
