Surface Plasmon Resonance (SPR) based fiber optic curvature sensors have the advantage of being insensitive to temperature and axial strain. However, they disadvantage low sensitivity small detection range. To improve performance SPR sensors, we propose an intensity-modulated microstructured optical (MOF) sensor. In this sensor, two no-core fibers (NCFs) are used as input-output couplers, MOF with silver film deposited is sensing arms. The light in cladding excite SPR, exciting resonant...

In order to broaden the sensing bandwidth of surface plasmon resonance (SPR) sensors, we propose and demonstrate a dual-channel SPR fiber optic sensor with wide bandwidth. The is fabricated using no-core (NCF), in which film consists silver ZnO film. characteristics are investigated by simulation experiment. wavelength range can be significantly tuned varying thickness experiments, that used for simultaneous detection temperature refractive index was realized cascading ZnO/Ag Ag experimental...
Abstract A twin-core photonic crystal fiber sensor is proposed for measuring liquid refractive index (RI) and temperature simultaneously. The air holes of the are arranged in a hexagonal pattern, two planes introduced by polishing cladding. On one side plane, gold film deposited RI measurement, on other side, polydimethylsiloxane measurement. We analyzed its sensing characteristics using finite element method. numerical results show that channels have no mutual interference arrangement...
When temperature and refractive index are measured in same spectrum, the measurement range of parameters is generally narrow due to bandwidth limitation. We proposed a sensor for simultaneous them wide wavelength this problem. The dual-channel structure based on photonic crystal fiber (PCF) with three air holes polished plane. silver film deposited plane responsible measurement, sodium polydimethylsiloxane (PDMS) filled an hole measurement. According research findings, two kinds metal films...
For surface plasmon resonance (SPR) sensors, sensitivity and full width at half maximum (FWHM) are incompatible parameters, it is difficult to realize a sensor with both high low FWHM. To weigh two we propose demonstrate an SPR based on few-mode fiber (FMF) structure. The FMF polished, which can enhance the evanescent wave leakage excite effect. Since this transmit only five modes, proposed characterized by Refractive index sensing experiments were performed it, results showed that polishing...
In order to meet the actual requirements for sensor miniaturization and integration, we propose a compact dual-parameter surface plasmon resonance (SPR) fiber sensor, which can simultaneously measure refractive index (RI) temperature of liquid. The is composed input–output couplers two sensing arms. no-core fibers (NCFs) microstructured optical (MOF) with deposited films are used as arms, respectively. One arm MOF silver film RI measurement, another that polydimethylsiloxane (PDMS)...
As an essential biomarker for diagnosing and treating various diseases, low-cost, quantitative detection methods complementary DNA (cDNA) have received much attention. The surface plasmon resonance (SPR) sensing technique is effective measurement scheme, but the ambient temperature pH variations a non-negligible impact. In this work, we developed triple-probe SPR system detecting cDNA concentration, temperature, pH. order to satisfy triple parameter measurements, used microstructured optical...
In order to cope with the crosstalk between temperature and refractive index (RI) caused by high-temperature environments, this study proposes modify surface plasmon resonance (SPR) fiber optic sensors molybdenum disulfide (MoS2). MoS2 efficiently modulates wavelength, enabling sensor operate in environments. The effect of film thickness on wavelength was investigated depositing no-core (NCF) using magnetron sputtering method. analysis shows that can induce a significant redshift dip, degree...
