| contents | This review systematically analyzes patent disclosures regarding plasmonic structures, devices, and integrated applications, highlighting the technology's capability to confine and manipulate electromagnetic energy at the nanoscale. Core materials rely on highly conductive noble metals (Gold, Silver), alongside innovative alternatives like Transparent Conducting Oxides (TCOs), Graphene, and 2D materials. These materials are engineered into diverse nanostructures that exploit Surface Plasmon Resonance (SPR) and Localized Surface Plasmon Resonance (LSPR). LSPR generates intense electromagnetic "hot spots" necessary for signal amplification (SERS) and provides extreme refractive index sensitivity for label-free detection. Key device elements include subwavelength plasmonic waveguides (hybrid and slot types) for optical signal routing. Dynamic control is achieved through active tuning mechanisms, utilizing electrical gating of charge carrier density (e.g., TCOs, Graphene) and solid-state phase change materials (e.g., VO2). |
