Tunable strong coupling of excitons in 2D semiconductors to surface plasmon polaritons
ORAL
Abstract
Two-dimensional transition-metal dichalcogenide (TMD) monolayers exhibit direct bandgap excitons with large binding energy. The optical response of TMDs is electrically tunable over a broad wavelength range, making these 2D materials promising candidates for optoelectronic devices. In this work, we integrate TMDs with various nanostructures fabricated on single crystalline silver thin films, and study the coupling between excitons in TMDs with surface plasmon polaritons (SPPs). We show that the coupling of exciton emission into SPPs can be utilized as to directly probe the dipole orientation of excitons in various TMDs. We further enhance the light-matter interactions by fabricating plasmonic crystal cavities, and demonstrate electrostatically tunable vacuum Rabi splitting in such a system.
