چکیده
A D-shaped fiber-optic surface plasmon resonance (SPR) sensor with MXene (Ti3C2Tx) is proposed as the sensing enhancement material. spin coating method was used to cover gold film fiber SPR a layer of MXene. Experimentally, sensor's sensitivity, full width at half maximum (FWHM), and figure merit (FOM) are discussed. The effect various concentrations on sensors investigated. results demonstrate that concentration increases, FWHM, FOM value increase well. MXene-based exhibits highest measuring 3143 nm/RIU, value, 15.26. Compared Au-film sensor, Sensitivity increased by 53.6%. indicate could be enhance performance refractive index sensors.

Fiber Optic Surface Plasmon Resonance based Refractive Index Sensor
In the present study, a surface plasmon resonance (SPR) based fiber optic sensor is proposed. The extreme sensitivity of SPR modes on the surrounding refractive index has been exploited to make the sensor. The optical fiber is coated with gold film which supports the propagation of surface plasmons. The SPR dip in the transmission spectrum is observed and its shift with varying refractive indic...

متن کاملFabrication and Characterization of the Fiber Optical Taper for a Surface Plasmon Resonance Sensor
For a fiber optical surface plasmon resonance (SPR) sensor a short part of its cladding should be removed to coat a thin layer of a metal. Usually this is problematic when an optical fiber with small core diameter is used. In this paper, a new method using µliter droplet of the HF acid for short fiber optical taper fabrication is reported. Using this method in a multi-mode optical fiber w...
متن کاملA Multi-D-Shaped Optical Fiber for Refractive Index Sensing
A novel class of multi-D-shaped optical fiber suited for refractive index measurements is presented. The multi-D-shaped optical fiber was constructed by forming several D-sections in a multimode optical fiber at localized regions with femtosecond laser pulses. The total number of D-shaped zones fabricated could range from three to seven. Each D-shaped zone covered a sensor volume of 100 μm dept...
