Abstract:

The objective of the proposed research is to develop active nanophotonic devices facilitated through the analysis and characterization of engineered dipole resonance modes in the nanostructures. I delve into various optical materials including semiconductors, dielectrics, and metals that serve as a premier material in the field of nanophotonic. Then the nano-sized structures, which are smaller or comparable to the wavelength of interest, are considered to sustain a well-defined resonance mode in the structure, such as surface plasmon and Mie-like resonance modes. These resonance modes stem from the dipole and multi-pole modes such as electric/magnetic dipoles, quadrupoles and so on. By exploring the resonance modes in the structures, mainly focused on the electric/magnetic dipole modes in this proposal, I propose a noble way to enable the tunability of the nonlinear optical effects in the semiconductor and dielectric materials. Furthermore, I will introduce a large chirality to a metamaterial by incorporating both electric and magnetic dipoles modes.
