FREQUENCY-SELECTIVE NANOSTRUCTURED PLASMONIC ABSORBER BY HIGHLY LOSSY INTERFACE MODE
Achieving high efficacy lighting at low cost is a key objective in terms of lowering our carbon footprint. Here we theoretically demonstrate for the first time highly lossy interface mode (HLIM), created by the interactions between a single thin metallic layer (TML) and slits arrays, can alter the lighting emissivity with the result of redirecting the Blackbody emission energy into the visible range providing world beating lamp efficacies for white light. In essence, a standard near white light (broadband) low efficacy incandescent bulb could be significantly enhanced by these surface plasmon polaritons to enable very high efficacies at low cost.
