“…The CTE of our IRF glasses, equal to 85.0–92.3 × 10 −7 K −1 as determined for the temperature range of 20–300 °C, is very low compared to the other types of phosphate glasses: 100 × 10 −7 K −1 [14] or even 120 × 10 −7 K −1 [15]. Such CTE difference can be explained with the presence of Yb 2 O 3 and two valent metal oxides, such as MgO and ZnO, which are introduced into our glasses, instead of an excessive amount of alkali oxide, but mainly with the presence of the glass network intermediate, Al 2 O 3 .…”

In the paper, we report on the development of a synthesis and melting method of phosphate glasses designed for active microstructured fiber manufacturing. Non-doped glass synthesized in a P2O5-Al2O3-BaO-ZnO-MgO-Na2O oxide system served as the matrix material; meanwhile, the glass was doped with 6 mol% (18 wt%) of Yb2O3, as fiber core. The glasses were well-fitted in relation to optical (refractive index) and thermal proprieties (thermal expansion coefficient, rheology). The fiber with the Yb3+-doped core, with a wide internal photonic microstructure for a laser pump, as well as with a high relative hole size in the photonic outer air-cladding, was produced. The laser built on the basis of this fiber enabled achieving 8.07 W of output power with 20.5% slope efficiency against the launched pump power, in single-mode operation M2 = 1.59, from a 53 cm-long cavity.

The Eu 3+ : 5 D 0 → 7 F 2 electric-dipol transition is known as hyper-sensitive transition which is indicator of symmetry of the RE ion site [10]. The I 616nm /I 519nm intensity ratio defined as symmetry parameter is c.a.…”

“…Phosphate glasses meet this criterion. Moreover, high solubility of rare earth ions in multicomponent phosphate glasses enables construction of short fiber amplifiers and light sources [8][9][10][11]. In case of up-conversion processes the efficiency of NIR to VIS conversion strongly depends on the type of used matrix, and in particular on the energy of phonon energy.…”

In the paper the analysis of luminescence emission in the VIS spectra range of fabricated multicomponent glasses doped with rare-earth ions and PMMA doped with dyes were presented. Up-conversion emission in: germanate glass co-doped with 0.5Yb 2 O 3 /0.75Eu 2 O 3 mol% under 976 nm excitation has been investigated. Down-conversion mechanism was analyzed in phosphate glasses doped with 0.5 mol% Tb 2 O 3 and PMMA codoped with fluorescein and rhodamine B. Phosphosilicate glasses doped with Er 3+ ions have been also studied in order to fabricate target for manufacturing planar waveguides by RF-sputtering deposition. Fabricated materials can be used for fabrication of optical fibers. In result blue up-conversion emission in double-clad optical fiber with Yb 3+ /Tm 3+ -doped core was presented.

“…Another essential aspect consisted in an increase of non-radiative decays probability, which is a consequence of high phonon energy of silica (1100 cm −1 ). Taking above into account numerous works have been done in order to develop a novel glass host for active optical fibres [8][9][10][11]. It has been shown that the choice of the glassy matrix for production of the active fiber has a crucial impact on its spectroscopic properties.…”

Abstract. In the paper the research on rare-earth doped and co-doped optical fibre conducted in the Laboratory of Optical Fiber Technology at the Bialystok University of Technology is presented. Novel active fibre constructions like multicore, helical-core and side detecting ribbon/core optical fibers were developed with a targeted focus into application. First construction i.e. multicore RE doped optical fibers enable supermode generation due to phase -locking of laser radiation achieved in a consequence of exchanging radiation between the cores during the laser action. In the paper a far -field pattern of 19 -core optical fiber-doped with Yb 3+ ions, registered in the MOFPA system, showed centrally located peak of relatively high radiation intensity together with smaller side-lobes. Another new construction presented here is helical-core optical fibers with the helix pitch from several mm and the off-set ranging from 10 µm to 200 µm. The properties of helical-core optical fiber co-doped with Nd 3+ /Yb 3+ were also discussed. In the field of sensor applications novel construction of a sidedetecting luminescent optical fiber for an UV sensor application has been presented. The developed optical fiber with an active core/ribbon, made of phosphate glass doped with 0.5 mol% Tb 3+ ions, was used as a UV sensing element.
