“…From Fig. 6, Dip-1 caused by MMI is red-shifted because of a positive RI change [33]. While, similar to most of in-line MZIs, the wavelength of Dip-2 exhibits a significant blue shift The corresponding RI wavelength sensitivity of Dip-1 and Dip-2 are 29.53 nm/RIU and -19.3 nm/RIU, respectively.…”

In this paper, an in-fiber composite modal interferometer (CMI) is proposed and experimentally demonstrated based on cascaded no-cladding fiber (NCF) and thin-core fiber (TCF) structure, which respectively corresponds to multimode interferometer (MMI) and Mach-Zehnder interferometer (MZI). The self-image effect of MMI is deeply analyzed and the interference fringes distribution of CMI is accurately designed by the selective the length of NCF and TCF. The comprehensive tests are then conducted and the experimental results show that interference fringes present similar temperature response but the apparent differences in strain and refractive index (RI) tests owing to the asymmetrical structure. MMI has a near-zero intensity sensitivity of strain and red-shifts with the increased RI. But MZI has the sensitivity of-19.3nm/RIU and a 4.94 dB increment in the range of 300-1100 με. Thus high-discrimination simultaneous triple-parameter measurement is achieved by means of joint wavelength and intensity demodulation. The proposed CMI has the merits of high sensitivity, low cost and ease of fabrication, and is very promising and potential for the engineering monitoring and sensing applications.

“…In 2019, Zhang et al proposed an RI sensors based on a tapered SNCS fiber structure (waist diameter 13 μm) with RI sensitivity of 686 nm/RIU within the RI range of 1.333-1.350 [208]. In 2020, Wang et al further proposed a folded-tapered SNCS fiber structure for simultaneous measurement of both RI (1191.5 nm/RIU) and temperature (0.0648 nm/°C) [209]. A functionalized tapered SNCS was used for human chorionic gonadotropin (hCG) detection, where an ultrahigh sensitivity was achieved with a detection limit of 0.0001 mIU/mL [210].…”

A singlemode-multimode-singlemode (SMS) fiber structure consists of a short section of multimode fiber fusionspliced between two SMS fibers. The mechanism underpinning the operation of an SMS fiber structure is multimode interference and associated self-imaging. SMS structures can be used in a variety of optical fiber systems but are most commonly used as sensors for a variety of parameters, ranging from macro-world measurands such as temperature, strain, vibration, flow rate, RI and humidity to the micro-world with measurands such as proteins, pathogens, DNA, and specific molecules. While traditional SMS structures employ a short section of standard multimode fiber, a large number of structures have been investigated and demonstrated over the last decade involving the replacement of the multimode fiber section with alternatives such as a hollow core fiber or a tapered fiber. The objective of replacing the multimode fiber has most often been to allow sensing of different measurands or to improve sensitivity. In this paper, several different categories of SMS fiber structures, including traditional SMS, modified SMS and tapered SMS fiber structures are discussed with some theoretical underpinning and reviews of a wide variety of sensing examples and recent advances. The paper then summarizes and compares the performances of a variety of sensors which have been published under a number of headings. The paper concludes by considering the challenges faced by SMS based sensing schemes in terms of their deployment in real world applications and discusses possible future developments of SMS fiber sensors.

“…In literature are present numerous experimental configurations that performs this kind of measurements, like the ones based on interferometers [3][4][5], no-core optical fibers [6,7], fiber Bragg and long period gratings [8][9][10], and many others [11][12][13][14]. Among all the others, Surface Plasmon Resonance (SPR) is often utilized as physical phenomenon to measure both refractive index and temperature at the same time [15][16][17][18].…”

In this work, a Surface Plasmon Resonance (SPR) multiparameter sensor for simultaneous determination of refractive index and temperature was manufactured through a novel and low-cost approach. A polymer planar optical structure was realized via inkjet 3D printing, by using photo-curable resins having tailored refractive index for device’s core and cladding, respectively. The multiparameter sensor was fully designed, manufactured, and experimentally tested to check the numerical analyses run on a preliminary phase. In such a way, a temperature resolution equal to about 0.5°C and a refractive index resolution equal to about 2 x 10^-4 RIU were obtained. Next, even a quality control analysis of the 3D printed surface was carried out by following a novel approach that relies on the profile monitoring technique, with the aim to evaluate the suitability of the design and the geometric accuracy control. In addition, thanks to the cost analysis performed through a properly model, it was proved that the multiparameter sensor designed, manufactured and tested satisfies the low – cost requirements, being the estimated cost ~ 23 €, which is an absolutely competitive cost if compared with other traditional sensors. In the end, even the performance of the sensor in terms of bulk sensitivity (equal to about 900 nm/RIU) resulted to be higher than similar devices already presented in the state – of – the – art, thus proving the validity of the developed SPR multiparameter sensor both in economic and performance terms.
