Abstract: A sub-wavelength scale optical lasing device, for the controlled transfer of a signal in nano- and other small-scale technologies. An array of sub-wavelength size holes is first milled, or otherwise embedded, into a thin metal film. This film is combined with optically active media to compensate for losses of the metal. Optical signals are emitted in the active media, and then transferred to the metal so that surface plasmon polaritons are excited. Lasing occurs as a result of the compensation of plasmonic losses by the available optical gain.
