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.

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.

The economic model of these journal publishing are categorized in three models. Supported by 1) societies and their members (members fee), 2) institutions such as universities or research institutes (institution budge), and 3) a combination of government and institutions (institution budges and government funding). The main return is from the institutional subscriptions. The cost performance of the system development for e-journals publishing is not yet proved. However, society members or people related to journal publishing for scientific communities are quite aware of that it is more important to have own publishing system/method (not only computer system but also a development of human resources) to allow them to control themselves rather than outsourcing whole publishing roles outside Japan. It is true that most of organization have been struggling to balance the cost, especially, the development expenses of e-journals system and the income from e-journals sales. It is still hard to battle to a myth of impact factor to authors and readers, but few of organizations have started to implement the COUNTER applicable by having a government funding support. “The Third Science and Technology Basic Plan” by Japanese government has introduced a budget, 25 trillion yen for coming 5 years. New journals are appearing. I would like to introduce a summary of these activities and share the real problems behind those economics.

From a macroscopic viewpoint, the dissipative soliton concept and an analogy with grassfire help us understand this strange phenomenon. The strong heat-induced absorption of silica glass and the highly confined supply of laser energy cause captured plasma to shift to the light source along the fiber leaving catastrophic damage behind it. From a microscopic viewpoint, the periodic void formation process was unveiled by the statistical analysis of void shapes and ultra-fast videography. The bullet-like shape of the damage train results from the formation of an intrinsic bridge inside the hollow silica melt behind the traveling plasma and the successive compression of detached voids under a steep 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.
