This phenomenon is useful to make irreversible optical limiting devices known as optical fuse.  The present structure breaks by 1.2-5.3 W of incident light (~1.5 um), exhibits low insertion loss of less than 1 dB, and is formed by dipping-up a small amount of hot glass melt between fibers, aligning the fibers and quenching them.  The relation between shape of the captured melt and its insertion loss is discussed.

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.

inserted between two ends of two silica glass optical fibers was
monitored via the intensity of a light passed through the circuit.  This
structure is used for a heat-induced optical fuse after the soft glass
layer has been coated with a light absorber.  Heat-induced breakage
occurred when the glass crystallized or flowed in the presence of a
shearing stress.  Without the stress, the optical link was maintained
through the glass melt but suddenly broke due to the crystallization.
On the other hand, the stress deformed the glass bridge and broke the
optical link less than 0.4 sec.  Thus, the shearing stress at the
splicing point helps the device respond immediately and reliably."		""	""	""	""	""	""	""	""	""	""	""	""	""	""	""	""	""	""	""	""	""	""	""	""	""	optical fiber//telluria glass//plastic flow//optical fuse	""	""	""	""	104446				web	web				2025-07-14 15:02:31 +0900	2025-07-14 15:47:29 +0900

This style of log-keeping brings about the situation that our experimental data and their descriptions are recorded separately into hard disks and papers, respectively.  Such a data separation is likely to be a serious rate-limiting factor in high-throughput experimentation from the view point of getting feedback on each researcher's work from what he has done.  We propose to utilize a blog (Weblog) as an electronic research notebook and discuss technical requirements for maintaining it, on the basis of the blogging experience for four years by one of the authors.  We need a user-installed blog server with authentication function for personalization and network infrastructure enabling us to ``blog anytime, anywhere''.  Although some knowledge-sharing systems have similar electronic notebooks as their front-end, the present blog system is different from these because it stores personal information which is not meant to be shared with others.  This blog-based notebook cooperates with these e-notebooks by promoting hyperlinks among their contents, and acts as a personal informatics workbench providing connections to all the resources needed.

glasses with parallel heat treatment under a temperature gradient
atmosphere in order to find the annealing condition to make transparent
glass ceramics in which Er3+ ions are located in the precipitated
crystals.  The preparation and annealing of the samples were performed
in a vertical temperature gradient furnace, where molten glass was
sucked into a pre-heated Pyrex glass tube.  The annealing temperature
range is between 350 degC and 800 degC.  After the annealing
treatment, time-resolved fluorescence emission of Er3+ (1.55um;
excitation light source is 977nm) were measured sequentially along the
tube.  The lifetime of the emission was about 2.6 msec for as-prepared
glass.  We have found that the lifetime increased to 5.2 msec when the
glass was annealed at 470 degC for 5 min and 550 degC for 5 min
successively, although its transparency was lost.  This increase implies
that the Er3+ ions are embedded in fluorine-rich phase to bring about
reduced non-radiative emission.  We are now continuing to find the
condition to get transparent glass ceramics.
