SOFT-COLLOIDS ON PLASMONIC SURFACES: OPTOTHERMAL TRAPPING AND ASSEMBLY
Abstract
The objective of this proposal is to study optothermal trapping, assembly and scattering from individual dielectric soft-matter based micro-colloidal architectures placed on a variety of plasmonic platforms. By utilizing optical tweezer methods, the PI intend to study the optical interaction between an isolated soft-microsphere that harbours whispering gallery modes, and a plasmonic thin film which facilitates surface plasmon polaritons. The PI will perform a parametric study as a function of composition, size, and shape-distortions of a microsphere, optical polarization of the incident and scattering beams, and as a function of plasmonic thin-film dimensions. The implication of this study is to understand optical and optothermal effects in soft metasurface systems, and has direct relevance in realizing flexible optical metamaterials platforms that can be interfaced with fluids.
