Nonlinear electrodynamics at exciton-plasmon interfaces: multiscale modeling and applications

Nonlinear electrodynamics at exciton-plasmon interfaces: multiscale modeling and applications Nonlinear electrodynamics at exciton-plasmon interfaces: multiscale modeling and applications The goal of the proposed research is to advance theoretical models of exciton-plasmon nanosystems in the nonlinear optical regime. Developed models will be used to perform multiscale simulations of various nonlinear optical processes ranging from gain enhanced nonlinear frequency conversion through second harmonic generation at plasmonic interfaces and its applications in detection to time-resolved nonlinear transient spectroscopy. Advances in modeling of exciton-plasmon systems improve our simulation capabilities to design new chemical and biological sensors and characterize nano-materials. Newly developed methodologies capable of quantitative description of nonlinear optical phenomena at the nanoscale can be used as an efficient design tool for broadband optical devices, nonlinear frequency converters, mid-infrared photonics, and THz sources and detectors.
