“…[4][5][6][7] Since the extraordinary optical transmission was demonstrated by Ebbesen et al in 1998, 1) much attention has been drawn to the research of metal transparency due to its potential application in transparency electrodes, 8) sensing 9) and cloaking. 10) To make the metal film transparent, a typical approach is to introduce holes or slits in both sides of the metal film, which could provide the efficient coupling of input and output light by exciting the surface plasmons. 11) Interestingly, narrow dips in the high transmission spectrum were also found to have wide applications in sensor field.…”

We propose a high-quality multispectral plasmonic sensor by coating a dielectric grating on the semiconductor-metal-semiconductor stacks. Ultra-narrow plasmonic resonances with the minimum bandwidth of 8 nm are insensitive to the polarization of incident light. The ultra-narrow multi-band phenomenon can be ascribed to the synergy of guided mode resonances, cavity modes and surface plasmon polaritons. The sensor displays superior refractive index sensitivity (404.295 nm/RIU) and figure of merit (50.3) and can also be used to detect the protein layer in sub-nanometer thickness. These offer new perspectives for achieving ultra-compact efficient sensors and filters.

“…Three distinct changes can be observed: 1) a new nearly-perfect absorption peak marked with Mode 4 (λ = 895 nm) appears in the near-infrared region, 2) the resonant band in the longer wavelength (Mode 3) is split into two bands, and 3) the intensities of all resonant bands decrease with ∆x. These phenomena can be ascribed to the structural symmetry breaking [1,25,44]. nanodisks are observed for these three resonant bands.…”

“…Metallic nanostructures have attracted incremental attention due to their unique optical properties such as extraordinary light transmission/absorption [1][2][3], Fano resonances [4,5] and cloaking [6,7] and thus can be widely applied in absorbers [8][9][10][11], sensors [12][13][14], and surface-enhanced Raman scattering [15][16][17][18], etc. These properties are dominated by the excitation of surface plasmons (SPs) including localized surface plasmons (LSPs) and propagating surface plasmons (PSPs) 3 These authors contributed to this work equally.…”

Ultra-narrow multi-band polarization-insensitive plasmonic perfect absorber for sensing

et al. 2020

View full text Add to dashboard Cite

We theoretically propose a simple ultra-narrow multi-band perfect absorber for sensing applications. The perfect absorber consists of periodically arranged metallic nanodisks etched with regular prismatic holes standing on the dielectric-metal bi-layer films. Multiple ultra-narrow perfect absorption bands are obtained in the near-infrared region with the maximum bandwidth less than 21 nm and the intensity as high as 99.86%. The ultra-narrow multi-band perfect absorption originates from the synergy of localized surface plasmons, propagating surface plasmons and lattice resonances. The perfect absorber also presents other significant advantages, e.g. polarization insensitivity and high sensitivity of surrounding environments. Moreover, the prominent sensing performance for detecting the trace amounts of glucose in water is demonstrated. These features make it a promising candidate with great potential in the fields of perfect absorbers, plasmonic sensors, filters and multiplexing binding bio-molecular detection.

“…Sinibaldi et al [122] reported that the SPP-BW based 1D photonic crystal performed better than the conventional SPP based sensors. Therefore, the periodic nanoparticle arrays have the potential to improve SPR sensing by introducing new concepts such as asymmetric shapes and novel structures [123,124]. Filho et al [78] developed an angle-resolved gratingcoupled smartphone-SPR sensor, which uses the screen of the smartphone as the light source.…”

The surface plasmon resonance (SPR) is a phenomenon based on the combination of quantum mechanics and electromagnetism, which leads to the creation of charge oscillations on a metal-dielectric interface. The SPR phenomenon creates a signal which measures refractive index change at the metal-dielectric interface. SPR-based sensors are being developed for real-time and label-free detection of water pollutants, toxins, disease biomarkers, etc., which are highly sensitive and selective. Smartphones provide hardware and software capability which can be incorporated into SPR sensors, enabling the possibility of economical and accurate on-site portable sensing. The camera, screen, and LED flashlight of the smartphone can be employed as components of the sensor. The current article explores the recent advances in smartphone-based SPR sensors by studying their principle, components, application, and signal processing. Furthermore, the general theoretical and practical aspects of SPR sensors are discussed.
