We have developed a series of all-dielectric metasurfaces to excite toroidal dipole or quasi-bound states in the continuum (quasi-BIC) modes for refractive index sensing. Meanwhile, the strong light-matter interaction within dielectric nanocavities, along with their high laser damage threshold, makes them highly suitable for nonlinear optical applications. For example, the interference of the multipolar resonant modes in dielectric metasurfaces was employed to achieve the generalized Kerker condition for efficient third-harmonic generation. The effects of the array size and oblique light incidence on THG performance, mediated by collective quasi-BIC modes, were investigated. Recently, to broaden the spectral range of nonlinear response, we also employed strong coupling between Mie resonance, quasi-BICs, and epsilon-near-zero mode in ultrathin Indium-Tin-Oxide film and achieve a ultrabroadband THG enhancement in the near-infrared. These nonlinear all-dielectric metasurfaces can be realized by complementary metal-oxide-semiconductor compatible process and are promising for on-chip integration in advanced nonlinear photonic applications.

內容摘要:
This talk presents nanopores as a nanofluidic platform for studying interfacial transport and molecular-scale dynamics. At the nanoscale, ion transport is dominated by interfacial effects, leading to behavior that deviates significantly from bulk systems. We first use nanopores as model systems to investigate how surface charge, electric double layers, and interfacial slip govern ionic transport and selectivity, with implications for energy conversion. Furthermore, we demonstrate how the same platform can be extended to probe single-molecule reaction dynamics and extract thermodynamic parameters, where confinement and external forces reshape molecular energy landscapes. Overall, nanopores provide a unified platform that bridges interfacial transport and molecular reaction dynamics across scales, connecting materials design with molecular-level physics.
