“…In recent times, photonic crystal fibre (PCF), also called holey fibre (HF) or micro-structured fibre (MF) has been widely used as a novel class of optical fibre for different sensing applications. Apart from the inherent advantages as a kind of optical fibres, PCFs exhibit their own pros, especially the ability to control its optical characteristics by manipulating the structural parameters of the optical fibre [10]. The PCF-SPR based sensors are now widely studied because of their simple and compact probe designed for high sensitivity, robustness, cost effectiveness, fast response, label-free detection [11].…”

In this paper, we design a 6-fold D-shaped photonic crystal fibre sensor based on the surface plasmon resonance (SPR). The coupling between fundamental core mode and three surface plasmonic modes which have different electric filed distributions for analytes of various refractive indices. We observe two different types of SPRs, namely, 'dielectric like' resonance with low-loss peak and 'plasmon like' resonance with high-loss peak, by analyzing the electric field distribution of the fibre modes. Further, we discuss the influence of the secondary SPR over the main SPR which is directly related to the detection performance of the proposed sensor. In order to mitigate the adverse effect of the sub-peak of the secondary SPR on the sensor's dynamic sensing range (DSR), we reduce the thickness of analyte's binding layer from 1500 nm to 500 nm. Thus, DSR can be extended to 44.4% from 1.33-1.41 to 1.33-1.45 at the cost of a reduced maximum sensitivity from 7900 nm/RIU to 5300 nm/RIU. Owning to the simple structure design of the proposed sensor, we envisage that this highly sensitive D-shaped PCF-SPR sensor could be developed as a versatile and competitive instrument with a large and flexible refractive index detection range.

“…For different fabrication methods and setups, the transmission-based SPR fibre biosensor and the reflection based SPR fibre sensors were both reported by Papiya Dhara et al, in 2015 [11]. Recently, with the development of photonic crystal fibre (PCF), PCF based biosensor has been one of the most popular devices for biochemical sensing due to its versatile applications and the ability to control the optical characteristics of the fibre through different photonic crystal structural design and structure parameters [12] [13]. In 2007, Hassani and Skorobogatiy reported a refractive index based SPR-PCF biosensor [14].…”

We propose a six-fold photonic quasi-crystal fibre with a trapezoidal analyte channel based on surface plasmon resonance for the detection of high refractive index liquid analytes and numerically analyse its sensing performance for different liquid analyte refractive indices and heights using the finite element method. In contrast to the common D-shaped structure photonic crystal fibre, we design a trapezoidal analyte channel to investigate the role of the sample liquid height within the channel and discussed the feasibility of the fabrication process. We find that with various liquid analyte heights ratio of 20%, 25%, 30% and 50% of the maximum channel height, the proposed biosensor exhibits linear sensing performance with a maximum refractive index (RI) sensitivity of 4400 nm/RIU, 6100 nm/RIU, 8000 nm/RIU and 17000 nm/RIU respectively, for analytes RI range of 1.44 to 1.57, 1.41 to 1.51, 1.40 to 1.49 and 1.40 to 1.44. This sensor is suitable to detect various high RI chemicals, biochemicals and organic chemical samples. Owing to its simple structure of the proposed biosensor with promising linear sensing performance, we envisage that this biosensor could turn out to be a versatile and competitive instrument for the detection of high refractive index liquid analytes.

A numerical analysis on dual core photonic crystal fiber (DC-PCF) based surface plasmon resonance (SPR) refractive index sensor is presented. The guiding parameters and required sensing performances are examined with finite element method (FEM) based software under MATLAB environment. According to simulation, it is warranted that the proposed refractive index sensor offers the maximum amplitude sensitivity of 554.9 refractive index unit (RIU −1 ) and 636.5 RIU −1 with the maximum wavelength sensitivity of 5800 nm/RIU and 11 500 nm/RIU, and the sensor resolutions of 1.72 × 10 −5 RIU and 8.7 × 10 −6 RIU, at analyte refractive index (RI) of 1.40 for x-and y-polarized modes, respectively. As the sensing performance in different wavelength ranges is quite high, the proposed sensor can be used in simultaneous detection for different wavelength ranges. Therefore, the proposed device is of a suitable platform for detecting biological, chemical, biochemical, and organic chemical analytes.
