Management of such data is generally very hard because each data is stored independently in various format. The data is structuralized and standardized by VSL, which has a hierarchy structure whose top layer has the same geometry of the combinatorial sample library. Each data is stored into the VSL systematically according to their coordinates in the library, the name of the measurements, and the dimension of the data. Thus, VSL can provide any data for analysis and visualization by specifying their identifying information. An actual example is demonstrated for the case of one-dimensional combinatorial glass sample library. Some tellurite glass libraries containing Er and F are annealed in a temperature-gradient furnace and the decay curves of 1.5 um-fluorescence of Er3+ are recorded along the libraries in order to find annealing conditions for precipitation of Er-containing fluoride crystals. Their fluorescence spectra, fluorescence lifetime, state of precipitates as a function of annealing conditions (7-dimensional data) are plotted in two figures through VSL.

This structure was made by splicing single-mode silica fibers through TeO2 glass melt to form a necked bridge, which was coated with carbon-containing paint after quenching it. Optical fusing action was induced by 0.3--1.5 W of CW light (1.54 um) and its output power dropped by 12 dB on average. Optical decoupling seems to be induced by not only deformation but also crystallization of the glass bridge. Its quite a high insertion loss of about 2dB can be reduced by introducing some refractive index modulations into the present structure.

To handle multi-dimensional data easily, a concept of virtual container for combinatorially acquired data is demonstrated which is called ``virtual sample library'' (VSL). VSL stores the data hierarchically in the order of (1) coordinates in the sample library, (2) names of the measurements performed, and (3) data obtained from each measurement. Thus, the stored data are accessed intuitively just by tracing this tree-like structure and are provided for visualization and sharing with others. This framework is constructed by the aid of an object-oriented scripting language which is good at abstracting complicated data structure. In this paper, after summarizing the problems of handling data acquired from combinatorially integrated samples and availabilities of software tools to solve them, the concept of VSL is proposed and its structure and functions are demonstrated on the basis of one specific experimental data. Its extensibility as a platform for numerical simulation is also discussed.

Fiber fuse was initiated in a glass ferrule in which the fiber end was in contact with cobalt oxide powder. Optical discharge emerged from a slowly moving darker radiant at about 300$\mu$m distance from the fiber end. Absence of void in the trajectory of the dark radiant implies that there is no glass-plasma interface at the radiant. Two other types of fused damage on ignition were also reported.

A number of optical micrographs showing front part of fiber fuse damage pumped by same energy were collected and sorted in the order of increasing distance between the top of the first big void and the top of the first regular void. The sorted sequence suggests the periodic void formation by the optical discharge; the discharge forms an asymmetric void and casts off its tail which shrinks to be one of regular voids. This process helps us to understand why the regular void looks like a bullet considering the internal pressure of the optical discharge and the temperature gradient along the fiber.

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 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."

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.

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''.
