Recent advancements in nanophotonics have revolutionized the manipulation and control of light at the nanoscale, opening up new frontiers in diverse scientific and technological domains. Precision-engineered nanostructures play a pivotal role in enhancing light-matter interactions, enabling functionalities previously unattainable. This field is characterized by the development of novel materials and devices that offer unprecedented control over optical phenomena at the sub-wavelength scale. The exploration of these nanostructures is crucial for pushing the boundaries of existing technologies and enabling future innovations. One significant area of progress involves the development of advanced metamaterials and plasmonic devices. These engineered structures possess unique optical properties that allow for precise manipulation of light, leading to applications ranging from advanced sensing and imaging to efficient light harvesting and optical circuit design. The ability to tailor light at the nanoscale with these materials is a cornerstone of modern nanophotonics [1].
Furthermore, the integration of quantum dots with nanophotonic systems represents a major leap forward. Quantum dots, with their tunable optical characteristics and high quantum yield, can be effectively coupled with other nanostructures like plasmonic nanoparticles and photonic crystals.
