“…An FBG created within the fiber with clad is not suitable for sensing because it lacks sensitivity, whereas removing the cladding from the FBG portion improves its performance, it is known as a etched fibre Bragg grating (eFBG). In recent times, surface plasmon resonance (SPR) and eFBG have been getting more attention because their cladding mode is more sensitive to changes in the refractive index (RI) of the surrounding medium [6][7][8][9][10]. This is something that standard FBGs can't do because they are limited by the medium around them.…”

This paper presented a sensitivity analysis of petrol adulteration. The benzene and xylene are mainly used as adulterants in petrol because of their low cost and easy miscibility. In comparison to traditional methods, the proposed etched fiber Bragg grating (eFBG) sensor is able to detect up to low-level adulteration efficiently when coated with a TiO2 layer. Adulteration in benzene-petrol and xylene-petrol is detected using concentration mixing with 10% increments in each case. The experimental outcomes of sensitivity and Bragg wavelength shifting were studied. TiO2-coated eFBG sensors achieved the sensitivities of 6.2 nm/RIU and 5.6 nm/RIU, which is 7% and 5% enhanced as compared to bare eFBG sensors in the case of benzene-petrol and xylene-petrol, respectively. This type of sensor is well-suited for on-road use in real-time.

“…The advantages of OFS includes pollution-free operation, corrosion resistance, remote sensing capability, immunity to electromagnetic interference, lightweight and small in size, high sensitivity, large bandwidth, and ease in light signal transmission (Joe et al, 2018;Qian et al, 2018;Giurgiutiu 2018). The OFS has been applied for measuring chemical and biochemical concentration (Zaca-Morán et al, 2018;Kadir et al, 2020;Zhu et al, 2020), adulterant traces (Singh, Ansari, and Raghuwanshi 2021;Singh, Iqbal Ansari, and Raghuwanshi 2020;Necochea-Chamorro et al, 2019), and relative humidity (Syuhada et al, 2020;Huang et al, 2018;Owji et al, 2021). (Agnarsson et al, 2009) To fabricate this optical miniature sensor, a part of the optical fibre cladding is modified and replaced with target measurand.…”

Optical fibre sensors have attracted a lot of interest in the field of sensors. However, the limitation of conventional optical fibre sensors such as high fragility and low sensitivity need to be considered. This work demonstrated a simulation of a new optical sensor design, a Cshaped optical fibre sensor to overcome these limitations. The design optimization of the sensor was conducted by changing the remaining cladding thickness ranging from 5 -0 µm and opening angle ranging from 70 -110°. The change in refractive index ranging from 1.30 -1.40 has been performed to evaluate the simulated sensing performance. The simulation results showed that reducing the cladding thickness and wider opening angle can improve the sensor's sensitivity. In cladding thickness optimization, the sensor showed the highest sensitivity with no remaining cladding thickness. In the opening angle optimization, the highest sensitivity can be achieved at the maximum opening angle of 110°, but the sensitivity changes due to the the opening angle range were minimal compared to cladding thickness optimization. The best Cshaped sensing performance with 0 µm remaining cladding thickness and 110° opening angle was selected to be compared to the closest in term of design which is the Dshaped optical fibre sensor. Overall, the Cshaped design has more cladding sector region left providing better physical robustness and has high potential to act as a new refractive index sensor with an estimated sensitivity of up to 2.77893 A.U, higher than the simulated Dshaped optical fibre sensor with an estimated sensitivity of 2.77468 A.U.
