Abstract:
Plasmonic condensers for generating surface plasmon at an evanescent wave surface can include a substrate layer, a metal layer comprising the evanescent wave surface; and a media layer disposed between the metal layer and the substrate layer. The media layer can be active or passive and can include a source of radiation that interacts with the metal layer to create surface plasmons that are not substantially optically detectable as far field radiation until an interfering object is brought into proximity with the evanescent wave surface. When an interfering object such as a sample or specimen is brought into proximity with the evanescent wave surface, it causes coupling of at least some of the surface plasmons into propagating radiation detectable by an objective lens. Systems, methods, and the like are disclosed, as are features of a plasmonic meta-materials illuminator.
