“…Of them the tri-layer Ag/SiO 2 /Ag plasmonic thermal emitter (ASA-PTE) has been demonstrated by Tsai et al [4] for its effectiveness for Bioinfrared light source. The emission optical properties of the ASA-PTE have been theoretically explained by approaches such as the momentum conservation law, dispersion relations of surface plasmon polaritons (SPPs) [1]- [3], SiO 2 thickness effect [5] surface plasmon type [6], lattice type [3], [7] and different dielectric materials on Si and sapphire substrates [7] as well. By extending the results of the above research, this work describes a novel Ag/SiO 2 /Ag structure to enhance the performance of ASA-PTE in areas such as a higher emission intensity and narrower FWHM.…”

This letter describes the successful fabrication of a novel tri-layer Ag/SiO 2 /Ag plasmonic thermal emitter with circular and square hole shapes at top silver film arranged in a hexagonal dimple array. The proposed design improves the emission intensity and reduces the full width half maximum. Experimental results indicate that the proposed design increases the emission intensity at 200°C from 30.5 to 42.3 mW/cm 2 for the hexagonal circular hole array, as well as increases the same intensity from 43.3 to 79.3 mW/cm 2 for the hexagonal square hole array.Index Terms-Surface plasmon polaritons, hexagonal dimple array, square hole array, full width half maximum (FWHM).

“…[6][7][8] Earlier studies have been focused on bowtie optical antennas with different shapes of metal patches and apertures. [9][10][11][12][13][14][15][16][17][18][19][20] Recently, rectangular metal bar optical antenna arrays have been investigated due to the easy tuning of the resonance wavelength and near-field spatial distributions through modifying antenna bar length, array period, and substrate.

A complete set of diabolo optical antenna arrays with different waist widths and periods was fabricated on a sapphire substrate by using a standard e-beam lithography and lift-off process. Fabricated diabolo optical antenna arrays were characterized by measuring the transmittance and reflectance with a microscope-coupled FTIR spectrometer. It was found experimentally that reducing the waist width significantly shifts the resonance to longer wavelength and narrowing the waist of the antennas is more effective than increasing the period of the array for tuning the resonance wavelength. Also it is found that the magnetic field enhancement near the antenna waist is correlated to the shift of the resonance wavelength.
