summarized.  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."

several hundred microns. No visible precipitates were found even in the
quenched melt of 100% TeO2. On the basis of reflection and
insertion loss measurements and a bending test, it is proved that
there's no micro crystals in the quenched melt segment which cause light
scattering and/or stress concentration.

Few tens nano liters of the melt were also inserted into a silica glass
capillary tube with the interior diameter of 126 $\mu$m, in order to
examine their tolerance to the residual stress induced on cooling due to
the large gap in thermal expansion coefficient between the two glasses.
Neither fracture nor bubbles were observed in the quenched melt inside
if its length is less than 2mm. This implies that tellurite melt can be
introduced into voids of sub-mm in size to integrate hybrid lightwave

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. This fabrication method is useful to make a connection between silica waveguides and non-silica glasses with poor thermal stability.
