“…(a), the sharp peaks at 415 and 656 cm −1 are observed in the spectrum of GC fiber core, corresponding to the characteristic Raman peaks of ZnAl 2 O 4 crystal . For the precursor fiber core, the Raman spectrum consists of several bands, which can be attributed to the bending vibrations of the bridging oxygen bonds of SiO 4 , Si–O–Si network and AlO 4 units in silicate multicomponent glasses . This result again indicates the absence of crystallization in precursor fiber but the presence of crystallization in the GC fiber.…”

Glass-ceramic fibers containing Cr 3+ -doped ZnAl 2 O 4 nanocrystals were fabricated by the melt-in-tube method and successive heat treatment. The obtained fibers were characterized by electro-probe micro-analyzer, X-ray diffraction, Raman spectrum and high-resolution transmission electron microscopy. In our process, fibers were precursor at the drawing temperature where the fiber core glass was melted while the clad was softened. No obvious element interdiffusion between the core and the clad section or crystallization was observed in precursor fiber. After heat treatment, ZnAl 2 O 4 nanocrystals with diameters ranging from 1.0 to 6.3 nm were precipitated in the fiber core. In comparison to precursor fiber, the glass-ceramic fiber exhibits broadband emission from Cr 3+ when excited at 532 nm, making Cr 3+ -doped glass-ceramic fiber a promising material for broadband tunable fiber laser. Furthermore, the melt-in-tube method demonstrated here may open a new gate toward the fabrication of novel glass-ceramic fibers.

“…The broad band located around 500 cm −1 corresponds to the Si-O-Si bending vibration modes of the [SiO 4 ] unit26272829. The band located around 600 cm −1 is associated with the Si-O-Si symmetric stretching vibration of [SiO 4 ] unit303132. The band ranging from 800 to 1000 cm −1 can be associated with the stretching mode of the short Ti-O* bond (O* denotes an apical oxygen), the Ti-O bonds (O-denotes a non-bridging oxygen)33.…”

A glass-ceramic optical fiber containing Ba2TiSi2O8 nanocrystals fabricated using a novel combination of the melt-in-tube method and successive heat treatment is reported for the first time. For the melt-in-tube method, fibers act as a precursor at the drawing temperature for which the cladding glass is softened while the core glass is melted. It is demonstrated experimentally that following heat treatment, Ba2TiSi2O8 nanocrystals with diameters below 10 nm are evenly distributed throughout the fiber core. Comparing to the conventional rod-in-tube method, the melt-in-tube method is superior in terms of controllability of crystallization to allow for the fabrication of low loss glass-ceramic fibers. When irradiated using a 1030 nm femtosecond laser, an enhanced green emission at a wavelength of 515 nm is observed in the glass-ceramic fiber, which demonstrates second harmonic generation of a laser action in the fabricated glass-ceramic fibers. Therefore, this new glass-ceramic fiber not only provides a highly promising development for frequency conversion of lasers in all optical fiber based networks, but the melt-in-tube fabrication method also offers excellent opportunities for fabricating a wide range of novel glass-ceramic optical fibers for multiple future applications including fiber telecommunications and lasers.

“…With increasing ZnO/SiO 2 molar ratio, the band at 45622 cm -1 is shifted towards 645 cm -1 and finally, splited into two components for 10 mol% ZnO content glasses[203]. The vibrations in the range 400 -650 cm −1 are caused by bending vibrations of the bridging oxygen (BO) bonds of SiO 4 and band near 779 cm -1 is caused by the Si -O -Si network, ZnO 4 tetrahedra and AlO 4 units with three BOs and one NBO.…”

“…In the spectra, a sharp band assigned at 808 cm -1 is the characteristic of B 2 O 3 and the band at 968 cm -1 is caused by vibrations of isolated PO 4 units in the structural 65 network of borophosphate glasses [197]. 15 glass is decreased [201][202][203][204]. The band at 506 cm -1 was disappeared above 4 mol% of TiO 2 .…”
