“…Moreover, the sensing response is obtained at one location of the sensor structure. This is a very attractive feature that reduces the complexity in interrogating several outputs provided by multiparameter optical sensors [29][30][31][32]. By allowing simultaneous measurements of multiple quantities at the same place of the fiber, rather than placing specialized sensors sequentially along the fiber, this approach extends the notion of distributed sensing.…”

The growing demand for multiparameter sensors includes compact devices accompanied by simple calibration processes to distinguish the outputs from each other. This paper evaluates a scheme to determine multiple parameters of a medium using localized surface plasmon resonances (SPR) excited on a Dshaped photonic crystal fiber (PCF) partially covered by two gold layers of different thicknesses. We demonstrate that the proposed sensing platform, once customized to characterize the possible dispersive profiles of the refractive index of the analyte, also allows interrogating the temperature of a sample from a linear relationship. Since the plasmonic resonances are excited at separated and low crosstalk spectral channels, different sensing responses can be obtained simultaneously in the same location of the D-shaped PCF. These features turn out the SPR sensor a suitable tool for simultaneous monitoring of optical dispersion and temperature.

“…In recent years, photonic crystal fiber (PCF) have been widely used in medical diagnosis [1][2][3][4], temperature sensing [5,6], environmental detection and other fields [7]. Various PCF structures have been discovered, such as D-shape structures [8], hexagonal inner metal coatings [9], multi-channel sensing structures [10], and outer metal coatings [11]. These structures can be roughly divided into two categories.…”

In this paper, a D-shape dual side-polished (DSP) photonic crystal fiber (PCF) sensor based on high sensitivity and high range refractive index (RI) is proposed and analyzed. The surface of the structure is plated with Au and TiO2, which can enhance the surface plasmon resonance (SPR) effect and sensitivity. The characteristics of the sensor were analyzed by finite element method (FEM). Its RI scope of detection is 1.38–1.42, and by optimizing geometric parameters, the optimal wavelength sensitivity (WS) is 22,100 nm/RIU. Additionally, the WS for DSP-PCF is far better than the recently reported PCF sensors in the above mentioned RI detection range to the best of our knowledge. With these significant outcomes over the analyte RI range, which is helpful for the fields of environmental detection and medical diagnosis.
