Extending the Propagation Distance of a Silver Nanowire Plasmonic Waveguide with a Dielectric Multilayer Substrate
Douguo Zhang, Yifeng Xiang, Junxue Chen +9
Chemical synthesized silver nanowires have been proved to be the efficient architecture for Plasmonic waveguides, but the high propagation loss prevents their widely applications.…
Diffraction-Free Bloch Surface Waves
Ruxue Wang, Yong Wang, Douguo Zhang +11
In this letter, we demonstrate a novel diffraction-free Bloch surface wave (DF-BSW) sustained on all-dielectric multilayers that does not diffract after being passed through three…
Plasmonic lasing of nanocavity embedding in metallic nanoantenna array
Cheng Zhang, Yonghua Lu, Yuan Ni +6
Plasmonic nanolasers have ultrahigh lasing thresholds, especially those devices for which all three dimensions are truly subwavelength. Because of a momentum mismatch between the p…
Controllable directive radiation of a magnetic dipole above planar metal surface
Zheng Xi, Yonghua Lu, Peijun Yao +3
We report unidirectional radiation of a magnetic dipole above planar metal surface, the radiation direction can be manipulated via changing the distance between the dipole and the…
Plasmonic dark field microscopy with a polymer substrate
Yikai Chen, Douguo Zhang, Lu Han +4
In this letter, a plasmonic dark field microscopy taking advantages of the polymer loaded surface plasmon polariton waveguide (PLSPPW) is experimentally demonstrated. The dye molec…
Direct characterization of planar waveguide modes by Fourier plane fluorescence leakage radiation microscopy
Douguo Zhang, Qiang Fu, Xiangxian Wang +2
In this letter, the leakage radiation microscopy (LRM) is extended into characterization of planar waveguide modes (WMs) rather than surface plasmon polaritons (SPPs) taking advant…
