New and more portable means of generating narrow band radiation is of interest, especially in the terahertz (THz) range. One potential method for generating radiation involves photo-mixing over nano/micro scale plasmonic structures. The plasmonic structures can serve as antennas for absorbing incoming photons and conversely emit radiation of a lower frequency. Designs include 2-dimensional and 3-dimensional arrays of theses resonant structures fabricated on Ag thin films using electron-beam lithography and lift-off. Patterns vary from arrays of structures of identical lengths and widths, to those with alternating and increasing lengths and widths. We have shown emission of visible radiation from similar structures when excited by space charge from electrons. The absorption and emission of light by the arrays has been measured. The effect of different antenna structures on the in absorption and emission will be discussed.
