“…So, the metal oxides such as Titanium dioxide (TiO2) could be a candidate material to detect the toxic substances due to its good properties such as high refractive index, highly light confinement, cost-effective, high stability and resistance to the corrosion and to the chemicals [21,22]. In addition, by using a conducting metal oxide such as TiO2 with Au, the operating wavelength of the sensor based SPR moves to NIR area [23][24][25][26] owing to lower carrier concentration of TiO2 (N'1020 cm −3 ) comparing to the Au (N'1023 cm −3 ). To evaluate the behavior of the fiber sensor, simulation methods are essential tools to analyze different parameters such as effective refractive index and the intensity.…”

An investigation on a single mode optical fiber sensor-based surface plasmon resonance was carried out in this work. A titanium dioxide (TiO2) coated gold Nano-column (Au) are deposited on the proposed sensor and theoretically analyzed using COMSOL Muliphysics software 5.3. Presence of TiO2 over the Au Nano-column can improve the sensitivity of the sensor and tune the resonance peak of transmission spectrum from visible region to near-infrared region. The size effect of TiO2 nanoparticles on the sensor performance is studied. The optimum parameters of such as Au size and separation width between the Au Nano-column have been selected to enhance the performance of the sensor. In comparison, the sensor with TiO2 over Au Nano-column is significantly improve the sensitivity and develop the sensor performance. The greater sensitivity of 5243.76 nm/RIU (refractive index unit) is obtained of sensor with TiO2 over Au Nano-column when the external refractive index of analyte is varying from 1.33 to 1.39, while sensitivity of the sensor coated with Au Nano-column is obtained to be 4643.17 nm/RIU for the same analyte range. Above results can be used to predict the best parameters values of the sensor that corresponding to the greatest sensitivities of detection and finally opening new study in the field of gas sensors. HIGHLIGHTS Optical fiber biosensors are a devices that use to measure the analyte by using the optical field Optical fiber biosensors have a high detection speed and low-cost, compared to congenital sensors The optical fiber sensors based SPR are widely used for biosensor applications The novelty in this research is the fabricate of optical fiber sensor coated with TiO2 over Au Nano-column based SPR foe gas detection GRAPHICAL ABSTRACT
