Plasmon Polariton

Surface plasmon polariton (SPP) waves exhibit local characteristics that can break diffraction limits; for this reason, the production of subwavelength optoelectronic device has been the focus of current studies. To determine the importance of surface plasmon wave applications, we aim to investigate whether or not the theoretical dispersion obtained in the plasma and metal (Drude model) exhibits the same expression, satisfy the relationship of SPPs by controlling the electron density of the plasma and the frequency of the incident electromagnetic wave, and derive the system performance parameters and plasma density parameters by changing the grating geometry and dielectric constant of the surrounding medium by using the grating structure based on surface plasmon propagation characteristics associated with sensor research. The simulation results of then design structure showed that transmission bandwidth rapidly decreases and transmission peak gradually decreases as metal dielectric thickness decreases. An SPP sensor can effectively eliminate light instability in the two wavelengths of light intensity difference to obtain anti-interference and improve the range of the measuring instrument by using two fiber-grating structure filters. Therefore, studies on surface plasmon devices for integrated application are of promotional importance.

We investigated experimentally the plasmon-enhanced photoluminescence of the amorphous silicon quantum dots (a-Si QDs) light-emitting devices (LEDs) with theAg/SiOx:a-Si QDs/Ag sandwich nanostructures, through the coupling between the a-Si QDs and localized surface plasmons polaritons (LSPPs) mode, by tuning a one-dimensional (1D) Ag grating on the top. The coupling of surface plasmons at the top and bottomAg/SiOx:a-Si QDs interfaces resulted in the localized surface plasmon polaritons (LSPPs) confined underneath the Ag lines, which exhibit the Fabry-Pérot resonance. From the Raman spectrum, it proves the existence of a-Si QDs embedded in Si-richSiOxfilm (SiOx:a-Si QDs) at a low annealing temperature (300°C) to prevent the possible diffusion of Ag atoms from Ag film. The photoluminescence (PL) spectra of a-Si QDs can be precisely tuned by a 1D Ag grating with different pitches and Ag line widths were investigated. An optimized Ag grating structure, with 500 nm pitch and 125 nm Ag line width, was found to achieve up to 4.8-fold PL enhancement at 526 nm and 2.46-fold PL integrated intensity compared to the a-Si QDs LEDs without Ag grating structure, due to the strong a-Si QDs-LSPPs coupling.
