105355	Rapid and quantitative determination of crystallization tendency of zinc tellurite glass melt by using temperature-gradient furnace					TODOROKI Shin-ichi//Matsumoto T.//Inoue S.

of glass sample library and anneal it successively under a temperature
gradient (200∼1050^∘C/40cm). A glass capillary tube (ID 1.5
mmφ× OD 8 mmφ) is used as a cell of the library. Zinc
tellurite melt at 800 ^∘C is sucked into the cell by applying a
vacuum pressure to the other side of the capillary. Crystallization is
observed as a white segment in the library under an appropriate annealing
condition. A set of 2D sample array is obtained by preparing several
sample libraries with different annealing time. Since this array itself
corresponds to a T-T-T (Time-Temperature-Transform) diagram, a tangent
which touches the crystallized region and pass through the melting
temperature at t=0 gives critical cooling rate, Q.

Compositional dependence of Q shows that the minimum of Q is not
located at the eutectic point of ZnO-TeO2 system, which has been
believed to be most stable composition on the basis of the known glass
forming regions, but is shifted to ZnO-rich region. Considering the
high reproducibility of this automated system and the large error bar of
previous results, this result is more reliable.

We also investigated the dependency of Q on thermal hysteresis. For
the melt once quenched below the glass transition temperature
(T\mathrmg) and annealed at above T\mathrmg, the Q value
becomes larger than that without the quenching. This is because the
former glass melt went through the nucleating temperature region located
just above T\mathrmg. It is concluded that this automated system
makes it easier than ever to examine quantitatively the thermal
stability of glass melt having low melting temperature, which is one of
the important factors for judging the feasibility of fabricating new
glass devises with desired quality."		""	""	""	""	""	""	""	""	""	""	""	""	""	""	""	""	""	""	""	""	""	""	""	""	""	""	""	""	""	""	104434				web	web				2025-07-14 15:02:29 +0900	2025-07-14 15:47:28 +0900

Once initiated, opical discharge runs along the fiber core region to the light source and leaves periodic voids whose shape looks like a bullet pointing the direction of laser beam.  The relation between damage pattern and propagation mode of optical discharge is still unclear even after the first in situ observation three years ago.

Fiber fuse propagation over hetero-core splice point (Corning SMF-28e and HI 1060) was observed in situ.  Sequential photographs obtained at intervals of 2.78 us recorded a periodic emission at the tail of an optical discharge pumped by 1070 nm and 9 W light.  The signal stopped when the discharge ran over the splice point.  The corresponding damage pattern left in the fiber core region included a segment free of periodicity.

The spatial modulation pattern of the light emission agreed with the void train formed over the hetero-core splice point.  Some segments included a bullet-shaped void pointing in the opposite direction to the laser beam propagation although the sequential photographs did not reveal any directional change in the optical discharge propagation.

(xTeO2-(100-x)ZnO, x=80,90,100 in mol%)
were inserted and quenched between two ends of silica glass optical
fibers to form a new optical coupling structure, whose length was
several hundred microns.  No visible precipitates were found even in the
quenched melt of 100% TeO2.  On the basis of reflection and
insertion loss measurements and a bending test, it is proved that
there's no micro crystals in the quenched melt segment which cause light
scattering and/or stress concentration.

Few tens nano liters of the melt were also inserted into a silica glass
capillary tube with the interior diameter of 126 $\mu$m, in order to
examine their tolerance to the residual stress induced on cooling due to
the large gap in thermal expansion coefficient between the two glasses.
Neither fracture nor bubbles were observed in the quenched melt inside
if its length is less than 2mm.  This implies that tellurite melt can be
introduced into voids of sub-mm in size to integrate hybrid lightwave
circuits.
