“…By utilizing the phase modulation and adopting phase interrogation method, the sensitivity has been determined to be 9.09 × 10 4 Deg/RIU, the theoretical value is higher than those of the conventional wavelength sensitivity. It is noteworthy that Xie et al [19,20] experimental researched the influences of side-polished depths and sensing layer thicknesses on D-shaped photonic crystal fiber surface plasmon resonance sensors, and concluded that the sensitivity increases as the sensing layer thickness increases. But it decreases slightly when the side-polished depth is going up with a certain range.…”

The refractive index sensing characteristics of the side-polished photonic crystal fiber (PCF) surface plasmon resonance (SPR) sensor are detailed investigated in this paper. We used the finite element method (FEM) to study the influences of the side-polished depth, air hole size, lattice constant, and the refractive index (RI) of the PCF material on sensing performance. The simulation results show that the side-polished depth, air hole size, lattice pitch have significant influence on the coupling strength between core mode and surface plasmon polaritons (SPPs), but have little influence on sensitivity; the coupling strength and sensitivity will significant increase with the decrease of RI of the PCF material. The sensitivity of the D-shaped PCF sensor is obtained to be as high as 21700 nm/RIU in the refractive index environment of 1.33-1.34, when the RI of the PCF material is controlled at 1.36. It revealed a new method of making ultra-high sensitivity SPR fiber sensor. Then we experimental demonstrated a SPR refractive sensor based on the side-polished single mode PCF and investigated the sensing performance. The experimental results of the plasmon resonance wavelength sensitivity agree well with the theoretical results. The presented gold-coated D-shaped PCF SPR sensor could be used as a simple, cost-effective, high sensitivity device in bio-chemical detection.

“…The structure of the fiber used by Cennamo and coworkers leads to wide transmittance lines as being compared with the wagon-wheel structure studied in the present work. Another D-shaped photonic crystal fiber was designed on the basis of SPR sensor technology by Chen et al [13] which resulted in a similar sensitivity as that of [12]. Wagon-wheel geometry sensor was also designed and studied by Haukakorpi et al [14] which resulted in the same sensitivity and resolution range as the present work.…”

An idea of the surface plasmon resonance (SPR) has been utilized for the design of highly sensitive sensors based on the wagon-wheel fiber technology. Such sensors are sensitive to changes in the refractive index of sample analyte. In this study, a three-strut wagon-wheel structure, coated with the gold layer of nano-sized thickness, has been proposed as the SPR sensor. Finite element method is employed to simulate and tune the proposed SPR's design, which leads to a highly sensitive and multichannel plasmonic sensor with the ability for a dual reading on a single analyte or simultaneous identification of two analytes. In this design, suitable thickness values for the gold layer and core struts are determined. Sensitivities of the detector due to the first resonance peak, second resonance peak, and the difference in resonance peaks are calculated to be 1120 nm/RIU, 1540 nm/RIU, and 420 nm/RIU, respectively, when analytes are placed in all three channels of the fiber. Sensitivity of the detector with respect to the second resonant peak for analyte in Channels 2 and 3 is also found to be 1252 nm/RIU when Channel 1 is filled with the reference. The sensitivity and resolution of the sensor increase as the refractive index of the analyte increases by almost a linear proportion. If the sensor is utilized to detect the difference in two peaks, it would substantially reduce the noise, and the best result is expected. The thicknesses of the struts and the gold layer are proper parameters to be tuned in designing the detector.

“…This property has been used to adjust the sensitivity range, as demonstrated for optical fiber sensors in which the LSPR of nanostructured gold surfaces served to monitor the refractive index variation of a medium contained inside channels coated with mesoporous silica films of varying thickness. [124] Due to the small sensing volumes contributing to LSPR shifts, precise control over device geometry is of key importance and consequently, methods to deposit thin silica layers onto plasmonic substrates have been developed. [125] Since silica also features compatibility with biological and biomimetic systems, such composite substrates consisting of gold nanodisks covered with a 5 nm silica layer could be further equipped with a lipid bilayer to monitor the binding of a cholera toxin.…”

Hybrid colloids consisting of noble metal cores and metal oxide shells have been under intense investigation for over two decades and have driven progress in diverse research lines including sensing, medicine, catalysis, and photovoltaics. Consequently, plasmonic core-shell particles have come to play a vital role in a plethora of applications. Here, an overview is provided of recent developments in the design and utilization of the most successful class of such hybrid materials, silica-coated plasmonic metal nanoparticles. Besides summarizing common simple approaches to silica shell growth, special emphasis is put on advanced synthesis routes that either overcome typical limitations of classical methods, such as stability issues and undefined silica porosity, or grant access to particularly sophisticated nanostructures. Hereby, a description is given, how different types of silica can be used to provide noble metal particles with specific functionalities. Finally, applications of such nanocomposites in ultrasensitive analyte detection, theranostics, catalysts, and thin-film solar cells are reviewed.
