“…The Q factor of the plasmonic mode decreases considerably with increasing temperature while the Q factor of the optical mode is independent of temperature. This simulation is consistent with the fact that metal absorption increases rapidly in plasmonic modes with increasing temperature for modes having an intensity maximum at the dielectric−metal interface, whereas an optical mode with an intensity minimum at the interface shows small change with temperature. ,,− In addition, the FDTD results strongly support the experimental measurements in which the plasmonic and optical lasing modes show a distinguishable temperature dependence of the threshold. The optical loss plays a critical role in determining the threshold dependence in the disk/nanopan structure, where the resonant wavelength and pumping conditions of the plasmonic lasing are similar to those of the optical mode at each temperature.…”

We report the experimental demonstration of an optically pumped silver-nanopan plasmonic laser with a subwavelength mode volume of 0.56(lambda/2n)(3). The lasing mode is clearly identified as a whispering-gallery plasmonic mode confined at the bottom of the silver nanopan from measurements of the spectrum, mode image, and polarization state, as well as agreement with numerical simulations. In addition, the significant temperature-dependent lasing threshold of the plasmonic mode contrasts and distinguishes them from optical modes. Our demonstration and understanding of these subwavelength plasmonic lasers represent a significant step toward faster, smaller coherent light sources.

“…The structural configuration of the 1-D plasmonic-crystal may have an advantage, especially for an experiment at a lowtemperature, by simply putting it on the cold finger of a cryostat, thereby providing the easy circumstance of vertical pumping and detection. However, the values of achievable Q-factors should be tested by future experiments, since one of the recent experimental results indicates a minimal temperature effect in lowering the metallic loss [28] as opposed to several theoretical predictions.

One-dimensional surface-plasmonic nanobeam cavities are proposed as a means to confine surface plasmons to a subwavelength-scale mode volume, while maintaining a relatively high Q-factor. By bonding one-dimensional photonic-crystal nanobeam structures to a low-loss metallic substrate, a clear plasmonic TM bandgap can be formed. The introduction of a single-cell defect alongside the engineering of side-air-hole shifts to this plasmonic-crystal nanobeam provides subwavelength-scale plasmonic mode localization within the plasmonic TM bandgap. This suppresses radiation and scattering loss to render a maximum Q-factor of 413 and a modal volume of 3.67x10(-3) microm3 at room temperature. The possibility of further reduction in the intrinsic loss of the cavity is investigated by lowering the operating temperature and the Q-factor of 1.34x10(4) is predicted at a temperature of 20 K for the optimistic case.

“…10 In this work, we study the possibility of controlling the SPP loss by low temperature. 11 According to the Drude model, imaginary part of dielectric permittivity of metal, e 00 , which primarily determines optical loss in plasmonics, is inversely proportional to the electron damping time s and dc Ohmic conductivity…”

Large temperature-independent components of the dc resistivity and the imaginary part of the dielectric constant at optical frequency are due to scattering on bulk and surface defects rather than on phonons. This suggests that the quality of metal should be improved first, after which a further improvement can be sought through the reduction of temperature. V C 2012 American Institute of Physics.
