Exciton-plasmon coupling in nanocomposites

Abstract

There has been growing interest in developing nanoscale optoelectronic devices by combining nanomaterials with complementary optical properties into composite (hybrid) structures. The number of possible nanocomposites that can be built from already existing nanostructures is simply enormous. A significant amount of research on nanocomposites has been devoted to the study of excitonplasmon interactions in metal-semiconductor nanostructures, which offer a wide range of opportunities to control light-matter interactions and electromagnetic energy flows on nanometer length scales. Strong exciton-surface plasmon coupling in metallic nanocomposites could lead to efficient transmission of quantum information between qubits for applications in quantum computing and communication. These nanocomposites also have applications in biophotonics, sensing and switching applications.
