??The development of reliable and integrated single-photon sources (SPS) represents a key milestone toward the implementation of quantum communications and information technologies. In this framework, point-like lattice defects in hexagonal boron nitride (hBN) flakes has recently attracted significant attention as a promising solid-state emitter platform; thanks to its room-temperature operation, high photostability, and compatibility with on-chip photonic architectures. The aim of this work is to investigate the coupling of defect-related emission in hBN flakes with optical modes sustained by engineered multilayer structures, specifically metal-dielectric multilayers supporting Tamm plasmons (TPs) and dielectric multilayers supporting Bloch surface waves (BSWs). ?? ??This activity involves theoretical modeling, clean room fabrication and experimental optical characterization.
