Description
Atomically thin transition metal dichalcogenides (TMDs) provide a unique excitonic platform for dielectric nanophotonics, combining strong light–matter interaction, pronounced nonlinearities, and internal valley degrees of freedom with inherent compatibility for planar integration. In this talk, we present recent advances in hybrid systems that integrate TMD monolayers with high-index dielectric nanostructures and metasurfaces, aiming at scalable architectures for enhanced and controllable optical functionalities. We discuss how Mie-type resonances and collective modes in dielectric platforms can be harnessed to tailor exciton emission, manipulate polarization and valley-selective responses. Particular emphasis is placed on fabrication strategies enabling deterministic and large-area integration, as well as on the role of coherence, carrier dynamics, and symmetry in governing hybrid light–matter interactions. These developments position TMD-based hybrid nanophotonic systems as a versatile route toward compact, tunable, and potentially quantum-enabled devices, bridging excitonic materials with next-generation dielectric metasurface technologies.
