Mode splitting of surface plasmon resonances in super-period metal nanohole gratings
Junpeng Guo, Haisheng Leong
We experimentally observed the surface plasmon resonance mode splitting in a super-period metal nanohole grating under the transverse magnetic polarization excitation. The mode spl…
Guided Surface Plasmon Mode of Semicircular Cross Section Silver Nanoridges
Junpeng Guo, Zeyu Pan
Tightly confined plasmon waveguide modes supported by semicircular cross section top silver nanoridges are investigated in this paper. Mode field profiles, dispersion curves, propa…
Investigation of Surface Plasmon Resonance in Super-Period Gold Nanoslit Arrays
Junpeng Guo, Haisheng Leong
Surface plasmon resonance in super-period metal nanoslits can be observed in the first order diffraction as well in the zeroth order transmission. In this paper, surface plasmon re…
Guided plasmon modes of triangular and inverted triangular cross section silver nanoridges
Zeyu Pan, Junpeng Guo, Richard Soref +2
Propagating two-dimensional plasmon modes guided along silver nanoridge waveguides with triangular and inverted triangular cross sections are investigated in this paper. Mode field…
Guided Plasmon Modes of Elliptical Cross Section Silver Nanoridges
Zeyu Pan, Junpeng Guo, Richard Soref +1
Propagating two-dimensional plasmon modes guided by elliptical cross section silver nanoridges are investigated in this paper. Mode field profiles, dispersion curves, propagation d…
Wideband Optical Filters with Small Gap Coupled Subwavelength Metal Structures
Boyang Zhang, Junpeng Guo, Robert Lindquist +1
In this letter, we show that the bandwidth of optical band-stop filters made of subwavelength metal structures can be significantly increased by the strong plasmonic near-field cou…
A wide-band perfect light absorber at mid-wave infrared using multiplexed metal structures
Joshua Hendrickson, Junpeng Guo, Boyang Zhang +2
We experimentally demonstrate a wide band near perfect light absorber in the mid-wave infrared region using multiplexed plasmonic metal structures. The wide band near perfect light…
