The present study proposes a photonic crystal fiber sensor based on a plasmon resonance. A thin gold metal layer was used as a plasmonic-active material to produce the surface plasmons to detect changes in the refractive index (RI) around it. The performance of the proposed sensor is evaluated by the finiteelement method for various refractive indices. The sensitivity of this sensor ranges from 3740 to 51227 nm/RIU for the RI range of 1.36-1.42 in the wavelength range of 700-1900 nm. Within this range, we observed the highest resolution, the best FOM, and amplitude sensitivity with values of 1.95 × 10 −6 RIU, 883.224 RIU −1 , and 2328.59 RIU −1 , respectively. This sensor has a simple structure and a better performance as compared with available sensors. The present study opens a new window to studies in the fields of biological materials, chemical materials, and the environment.

“…Moreover, because of the low curvature losses, which are not achievable with conventional waveguides, recently, SPPs attracted more attention from researchers. Hence, SPPs are regarded as the best candidate to design miniaturised photonic integrated circuits (PICs) [2,3]. In recent years, various plasmonic SPP-guiding structures have been emerged including nanowires [4], nanogrooves [5], metal wedges [6] and so on.…”

The authors propose a nanoplasmonic structure based on metal-insulator-metal (MIM) waveguides which consists of a 3 db power splitter and a side-coupled nanocavity placed between its two output ports. The proposed structure is analysed by the resonant theory and dispersion relation. Transmission spectra of the presented device are also extracted using the finite difference time domain method. Numerical simulations demonstrate that the structure operates as a band-stop filter in each output channel. Moreover, the resonance wavelengths can be tuned by adjusting the geometrical parameters of the nanocavity. Meanwhile, the authors developed the cavity and added an extra stub to it to append a new stopband to the output spectrum. Each resonance wavelength can be easily manipulated by changing the widths of the nanocavity and the added stub. In the end, by choosing two different lengths for the side-coupled cavities, the authors convert the power splitter into a wavelength division multiplexer. These introduced MIM, the authors proposed here, may have various meaningful applications in nanoscale high-density photonic circuits such as optical switches, logic plasmonic circuits and slow-light devices.

“…Although the bandwidth can be increased by cascading resonant elements [13,14], the phase profile across the entire surface is frequencydependent and changes either rapidly or slowly depending on the quality factor of the element resonance, hampering widespread applications.…”

We propose truly achromatic metasurfaces at midinfrared and visible spectra using plasmonic and all-dielectric concepts, respectively. The constituting layered elements, with each layer being a capacitive or an inductive structure, behave like low-pass circuit filters with almost linear phase response over the designed spectrum. This allows successful broadband operation. The plasmonic layered elements are limited to work around 50 THz due to the appearance of a plasmonic resonance feature at higher frequencies. On the other hand, the all-dielectric concept can be designed up to the visible range with negligible material dispersion. Design procedures and working principles are fully detailed. Two types of metasurfaces patterned by plasmonic and all-dielectric elements are carefully designed and numerically simulated around 50 and 600 THz, respectively. Chromatic aberration is successfully avoided. The plasmonic metasurface operates well in 5.5-7.5 μm, and the all-dielectric case has the desired performance over almost the entire visible band.
