and quenched between two ends of silica glass optical fibers to form a
optical coupling structure, whose length was several hundred um.
Dispite the large gap of thermal expansion coefficient between these
glass materials, neither fracture nor bubbles were observed, which
usually lead to a large optical propagation loss.  The insertion loss
was less than 10 dB, which was mainly due to the lack of an optical
waveguide structure in the tellurite glass segment.  Further loss
decrease is expected to be possible by introducing a refractive index
modulation.

    determined based on the time-temperature-transfer (T-T-T) diagrams,
    which are compiled by analyzing the crystallized area in the glass
    sample libraries annealed simultaneously by a furnace with
    temperature gradient.  This method reduces the laborious routine
    work for preparation, which is needed in the conventional method.
    Since the surface/volume ratio of the present samples is large,
    their crystallization is mainly governed by heterogeneous
    nucleation.  Thus, the Q values in this study can be used as a
    practical index for the glass products whose surface should be free
    of being ground and/or polished, such as fire-polished lenses,
    optical fibers and waveguides.

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."		""	""	""	""	""	""	""	""	""	""	""	""	""	""	""	""	""	""	""	""	""	""	""	""	""	""	""	""	""	""

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
