Low-Threshold Surface-Plasmon-Polariton Laser Pumped by Surface Plasmon Polaritons
Conference on Lasers and Electro-Optics, 2017We demonstrate a narrow-linewidth, low-threshold surface-plasmon-polariton (SPP) laser based on a low-loss open cavity resonator leveraging grating-coupled SPPs to pump the lasing SPPs with strong spatial overlap and minimum perturbation.

Regenerated surface plasmon polaritons
Applied Physics Letters, 2005We discuss a way to increase surface plasmon polariton (SPP) propagation lengths and intensities. It involves reflecting radiation loss back to the propagation surface, regenerating SPPs. This is achieved with a metal-dielectric structure, which is also designed to efficiently couple in external light.

Surface plasmon-polariton amplifiers
2012 14th International Conference on Transparent Optical Networks (ICTON), 2012Propagation of surface plasmons at metal surfaces is receiving much interest nowadays because of its broad range of potential applications, like subwavelength photonics or biosensing. Although plasmonic devices achieve unique properties, surface plasmons suffer from high attenuation because of the absorption losses in the metal.

Raman imaging with plasmon surface polaritons
Thin Solid Films, 1993Abstract We report on plasmon surface polariton (PSP) field-enhanced Raman spectroscopy with a two-dimensional detection system that allows microscopic imaging of ultrathin films. The technique offers a means to distinguish between coatings which are optically almost identical films but which have different Raman scattering characteristics.

Nonlinear Surface Plasmon Polaritons
Advanced Photonics Congress, 2012We present analytical analyses of the nonlinear interaction of SPP fields at a silver-vacuum interface, in the presence of a third order optical susceptibility in the metal. Both sum- and difference-frequency generation interactions are addressed.

SURFACE PLASMON POLARITON LOCALIZATION
Surface Review and Letters, 2008Localization of surface plasmons polariton is reviewed in the context of experiments and modeling of near-field optical images. Near-field imaging of elastic (in-plane) surface plasmon scattering is discussed, and approaches for the correct image interpretation are outlined.

Surface plasmon polariton discrete diffraction compensation
Optics Letters, 2009We report on the observation of discrete diffraction in surface plasmon polariton waveguide arrays at a wavelength of 1550 nm. We also adopt the effective index method to reduce our simulation geometry to two-dimensions, predict the spread of single-waveguide excitation in parallel waveguide arrays, and explore changing the excitation angle to detune ...

Polarization-Directed Surface Plasmon Polariton Launching
The Journal of Physical Chemistry Letters, 2016The relative intensities of propagating surface plasmons (PSPs) simultaneously launched from opposing edges of a symmetric trench structure etched into a silver thin film may be controllably varied by tuning the linear polarization of the driving field.

Introduction to Surface Plasmon-Polariton Waveguides
2010This chapter summarizes basic properties of the main Surface plasmon polariton (SPP) modes. SPPs are electromagnetic (EM) excitations that, being coupled to surface collective oscillations of free electrons in a metal, are bound to and propagate along metal-dielectric interfaces.
