摘要： 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.

摘要： Semiconductor lasers comprise a substrate; an active layer configured to generate transverse magnetic (TM) polarized light under an electrical bias; an upper cladding layer; a lower cladding layer; and a distributed feedback (DFB) grating defined by the interface of a layer of metal and a layer of semiconductor under the layer of metal, the interface periodically corrugated in the longitudinal direction of the laser with a periodicity of ΛDFB=mλ/(2neff), wherein m>1. The DFB grating is configured such that loss of one or more antisymmetric longitudinal modes of the laser structure via absorption to the DFB grating is sufficiently maximized so as to produce lasing of a symmetric longitudinal mode of the laser with laser emission characterized by a single-lobe beam along each direction defined by the grating diffraction orders corresponding to emission away from the plane of the grating.

摘要： An optical amplifier suitable for coherently amplifying surface plasmon-polariton waves with high gain and low noise over visible and infrared wavelengths. The optical amplifier is comprised of a thin strip of material having a complex permittivity with a negative real part, in contact on at least one side with an optical gain medium, where the strip has finite width and thickness such that optical radiation couples to the strip and propagates along its length as a surface plasmon-polariton wave. The surface plasmon-polariton amplifier can also be incorporated into a resonant cavity to form a plasmon-polariton laser.
