“…Ebbesen’s experiment proved that the EOT phenomenon is due to the coupling of incident light and surface plasmons (SPs). This provides a new method for further applications of novel photon devices such as biochemical sensing [ 4 ]. As many studies have verified, EOT can be realized by a subwavelength aperture on a metal film on account of the surface polariton plasmons (SPPs) [ 5 , 6 ].…”

In this work, we demonstrate a novel structure that can generate extraordinary optical transmission with a silicon hemisphere placed on a conventional bull’s eye structure. There is a single subwavelength aperture surrounded by concentric periodic grooves on a substrate. The extraordinary optical transmission in this work is realized by the coupling of the surface plasmon polaritons in the periodic grooves and the localized electromagnetic field generated by the Mie resonance in the silicon hemisphere. The maximum normalized-to-area transmission peak can reach up to 662 with a decreasing device area and size. The electromagnetic field distribution at different geometry parameters is analyzed to clarify the mechanisms of the work in this paper. Additionally, the use of dielectric material in the aperture can avoid ohmic losses of metal material compared with the conventional one, which may suggest that a wider range of bull’s-eye-structure applications is possible.

The interest to application of various surface plasmon resonance (SPR)-based sensors for the investigation of chemical and biological processes in thin layers deposited on the grating's surface/media is developing. Characterisation of processes as well as specimen's features might be performed analysing variations in optical properties (refraction index) of these thin layers. SPR sensors by default are characterised by high resolution and small uncertainties, and measurements might be performed in situ High-resolution, low-cost, SPR-based dosemeter concept has been proposed and realised depositing dose-sensitive nPAG gel layer onto diffraction grating's surface. The experimental set-up and method for information read out from the sensor were developed and implemented. Obtained results show a potential application of SPR-based dosemeter for dose measurements/mapping in steep gradient fields and/or large area fields.
