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.

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.

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.

The quenched melt seems to be free of precipitates because they would bring about larger loss if existed. The loss due to imperfect optical coupling between the fibers is estimated to be about 1 dB, which can be reduced by introducing some refractive index modulation into the present structure.
