Research Interests
Mie resonance
We are developing a colloidal solution of crystalline silicon nanospheres.[ref] Silicon nanostructures (100-200 nm) are capable of strong light-matter interaction due to Mie resonances. We are trying to control radiation properties of coupled emitters and scattering properties (spectral response, directionality, etc.) of silicon nanostructures by tailoring structural parameters or engineering electromagnetic environment.
Plasmonics
Free electrons in metal nanostructures can efficiently couple to light by surface plasmon resonances (SPRs). We are proposing novel plasmonic structures that have various functionalities. Computer simulations are used to predict optical properties: boundary element method (BEM), FDTD and FDFD.
Upconversion nanomaterials
Rare-earth doped materials show fascinating phenomenon, photon-upconversion. They can convert near-infrared photons into visible ones. We are developing nanocomposites composed of plasmonic and upconversion nanomaterials in order to boost upconversion intensity because the efficiency of upconversion nanomaterials are typically very low (~1%).
