“…It is important to mention that in some of the previous contributions the researchers have corroborated the fiber diameter measures through conventional digital microscopes [13,14,16,18,20,21]. This represents a low cost way to measure the fiber diameter.…”

The present research exposes a novel methodology to manufacture fiber optic sensors following the etching process by Hydrofluoric Acid deposition through a real-time monitoring diameter measurement by computer vision. This is based on virtual instrumentation developed with the National Instruments® technology and a conventional digital microscope. Here, the system has been tested proving its feasibility by the SMS structure diameter reduction from its original diameter of 125 μ until approximately 42.5 μm. The results obtained have allowed us to demonstrate a stable state behavior of the developed system during the etching process through diameter measurement at three different structure sections. Therefore, this proposal will contribute to the etched fiber optic sensor development that requires reaching an enhanced sensitivity. Finally, to demonstrate the previously mentioned SMS without chemical corrosion, and the etched manufactured SMS, both have been applied as glucose concentration sensors.

“…Compared with Refs. [11][12][13][14][15]19,[22][23][24], the proposed SMPMS temperature sensor shows a high sensitivity of 2.366 nm/°C. At the same time, compared with the sensing structure of the reference, this structure has the advantages of higher sensitivity, simple manufacture and low cost.…”

A fibre loop mirror sensor is proposed and demonstrated for strain and temperature measurements in experiment. In these schemes, fibre loop mirrors are constructed with single-mode-multimode-polarization-maintaining-multimode-single-mode optical fibre (SMPMS) structures. The strain and temperature characteristics of the sensor, depending on the lengths of multimode fibre (MMF) and polarization-maintaining fibre (PMF), are studied in the experiment. The results indicate that PMF and MMF lengths have less impact on strain sensitivity but a remarkable impact on temperature sensitivity, which is consistent with the theoretical analysis. The best strain and temperature sensitivities of an SMPMS structure sensor can reach up to 39.0 pm/με and 2.366 nm/°C, respectively. The sensors have the merits of easy fabrication, cost-efficiency and high temperature sensitivity and are quite suitable for fields requiring high-precision measurement.

“…Since 2020, a few researchers have started introducing CSF with unique modifications such as Vshaped, S-shaped, wave-shaped, short-tapered shaped, and half-coated PDMS on D-shaped fiber, thus offering a state of art on CSF design [4][5][6][7][8]. These new designs are robust and have successfully overcome the fragility of the conventional CSF design such as adiabatic tapered-shaped and wet 88 chemical etched-shaped fiber [9][10][11][12]. Moreover, unlike the coated CSF, the unique modification does not require a sophisticated fabrication process [13][14][15].…”

Coreless silica fiber has garnered a lot of attention in the field of sensors. Nevertheless, the limitation of conventional and unique coreless silica fiber sensors such as complex simulation, and high fragility of its physical structure needs to be considered. This work presents a simulation of a new coreless silica fiber design in a form of a trenched coreless silica fiber sensor to overcome these limitations. To optimize the sensor’s design, the trench depth was changed in the range of 0 μm to 50 µm at a fixed trench width of 50 μm. The change in analyte refractive index ranging from 1.3000 RIU to 1.4000 RIU was performed to evaluate the simulated sensing performance which showed that the increase in trench depth improved the sensor’s sensitivity with 50 μm being the trench depth at which the highest sensitivity was recorded. Later, the results obtained was compared to the closest in term of design which is the standard coreless fiber. Overall, the trenched coreless silica fiber design provided better sensitivity and is highly capable as of has a new refractive index sensor with an estimated sensitivity of up to 6.62726x10-7, higher than the simulated standard coreless fiber sensor with that of 2.22053x10-7.
