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.

On the basis of real-time observation of their fusing action, the mechanism of losing its transparency is discussed. The observed loss drop is found to be an overlap of decoupling of the circuit and transient light flux from the burned coating. The critical input power to blow out is expected to be raised by eliminating its insertion loss.

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.

Their pump power dependences were investigated using a 1.48 um laser light at powers ranging from 1.1 to 9.0 W. Periodic voids were left by an optical discharge that was in a cavity with a tail. The tail appears because the optical discharge is strongly enclosed in core region. Another mode of periodic void formation was found at near the threshold pump power for fiber fuse propagation. The optical discharge in this case also forms a transient tail during the void formation cycle.

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."
