This work presents fabricated silica microstructured optical fiber with special equiangular spiral six-ray geometry, an outer diameter of 125 µm (that corresponds to conventional commercially available telecommunication optical fibers of ratified ITU-T recommendations), and induced chirality with twisting of 200 revolutions per minute (or e.g., under a drawing speed of 3 m per minute, 66 revolutions per 1 m). We discuss the fabrication of twisted microstructured optical fibers. Some results of tests, performed with pilot samples of designed and manufactured stellar chiral silica microstructured optical fiber, including basic transmission parameters, as well as measurements of near-field laser beam profile and spectral and pulse responses, are represented.

The article considers the aspects of nanoscale Gd2O3:Nd3+ phosphors synthesis using the liquid polymer-salt method. Within the framework of the method, the double role of polyvinylpyrrolidone (PVP) as an organic solvent in the process of synthesis was determined. On the one hand, PVP stabilizes the process of Gd2O3 crystals formation, preventing their uncontrolled growth and aggregation. On the other hand, PVP serves as a fuel during decomposition (combustion) increasing the temperature of reaction and thus influencing the structural and emission properties of phosphors. It is shown that drying of the initial homogeneous solution containing gadolinium and neodymium salts and PVP at the room temperature for 24 hours followed by thermal treatment at the temperature of 1000 °C for 2 hours allow formation of highly luminescent Gd2O3:Nd3+ near-infrared phosphors. The crystals grown are characterized mainly by the cubic structure and an average size of 40 nm. Experimental results confirmed that the developed method is appropriate for modification of a structure of silica hollow-core antiresonant fibers with thin-film coatings based on the synthesized material and does not result in structural and phase conversion of Gd2O3 crystals. It is found out that emission spectra of nanoscale Gd2O3:Nd3+ phosphors formed by the polymer-salt method at the temperatures of 550 °C and 1000 °C are identical, as follows: 1) the shape of the luminescence peaks is the same for the two mentioned regimes of thermal treatment regardless of intensity, 2) the main luminescence peak is located near the wavelength of 1064 nm and corresponds to a 4F3/2-4I11/2 electron transition, 3) additional luminescence peaks are located close to 900 nm and 1340 nm and refer to 4F3/2-4I9/2 and 4F3/2-4I13/2 electron transitions respectively.

We present new type of silica graded index laser-optimized multimode optical fibers (LOMF) with extremely enlarged core diameter up to 100 μm and “typical” “telecommunication” cladding diameter 125 μm. This optical fiber was designed for harsh environment Gigabit onboard cable systems and industrial networks. It differs by special optimized graded refractive index profile, providing low differential mode delay (DMD) for selected guided modes. We present some results of tests, performed for manufactured pilot 520 m length of described LOMF 100/125, concerned with its geometry properties as well as key transmission parameters—attenuation and DMD map.

The model of a fiber optic sensor device which operational principle is based on the thermal quenching of luminescence for ambient temperature measurements was experimentally studied. The construction of a multimode optical fiber with a transmission of more than 90%/m in the spectral region from 350 to 650 nm and a quartz capillary filled with a photoactive polymer composition based on epoxyacrylate and the europium complex with 2-naphthoyltrifluoroacetone and trioctylphosphinoxide was used as a sensitive sensor element. An exponentially decreasing character of the temperature dependence of the luminescence intensity was discovered for the photoactive composition incorporated into the sensor (excitation wavelength, 355 nm; luminescence wavelength, 615 nm) within a range from 20 to 100°C. A quasi-linear change in the luminescence intensity depending on the power of the launched UV radiation was determined.
