“…Sample A is the most typical material among the series of transparent elastomers Shin-Etsu produces. Rhodamine 6G is a typical dopant fluorophore that has been used in POFs for various purposes [4,8,9]. It was dispersed in cyclopentanone before use.…”

“…Here, we report a fluorophore-doped FO sensor structure using polydimethylsiloxane (PDMS) elastomers. Previously reported sensor had PMMA (Poly(methyl methacrylate)) as the fiber material [4]. Poly(methyl methacrylate) was a proper material to demonstrate the sensor principle but had shown poor sensitivity on its own due to its hardness.…”

“…We selected a PDMS pair that forms an excellent core-cladding interface and is also capable of hosting fluorophores. With the goal of producing an FO strain sensor with fewer components, we previously reported a strain sensor made from a polymeric optical fiber (POF) that works with environmental white light and inspection by eye [4]. The POF contains rhodamine 6G (R6G) and coumarin 540A in its cladding and core, respectively.…”

A fiber-optic strain sensor that can show strain via color change and which can be viewed using human eyes has demand in the civil engineering field for alerting purposes. A previous sensor was fabricated using PMMA (Poly(methyl methacrylate)), which had the exceeding hardness to exhibit satisfactory sensor performance. In this research, an elastomer-based fiber-optic structure was fabricated to enhance the elastic response of such sensors and to enlarge the waveguide cross section. Various organic fluorophores were added to the core and cladding regions of the elastic waveguide to induce energy flow from the core to the cladding when stress is applied to the waveguide. Elastomer pairs suitable for the core and cladding were selected from among several candidate materials having high transparency. A method of dispersing fluorophores to each host elastomer and constructing an excellent core–cladding interface using the selected materials was proposed. To investigate the time-dependent changes in the fluorescence of the doped elastomer waveguide, the absorption and emission spectra were monitored after the host elastomers were cured.

“…Some of these dopants can generate or amplify visible light at the low-attenuation windows of POFs [5,6]. The emission and absorption features of these dopants can be suitable for achieving luminescence in the visible region of the spectrum, which is interesting for a wide range of applications [7,8,9]. Consequently, research on doped POFs is on an upward trend.…”

“…Consequently, research on doped POFs is on an upward trend. The results obtained are being applied for the development of optical sensors [7,8], of solar concentrators that collect and transport solar light [9], and of superluminiscent speckle-free light sources [5,10]. Additionally, the use of optical fibers allows for symmetrical output beams, due to their circular symmetry, and for longer interaction distances between light and dopant, owing to the guidance of light.…”

This paper employs the solution-doping technique for the fabrication of active polymer optical fibers (POFs), in which the dopant molecules are directly incorporated into the core of non-doped uncladded fibers. Firstly, we characterize the insertion of a solution of rhodamine B and methanol into the core of the fiber samples at different temperatures, and we show that better optical characteristics, especially in the attenuation coefficient, are achieved at lower temperatures. Moreover, we also analyze the dependence of the emission features of doped fibers on both the propagation distance and the excitation time. Some of these features and the corresponding ones reported in the literature for typical active POFs doped with the same dopant are quantitatively similar among them. This applies to the spectral location of the absorption and the emission bands, the spectral displacement with propagation distance, and the linear attenuation coefficient. The samples prepared in the way described in this work present higher photostability than typical samples reported in the literature, which are prepared in different ways.
