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.

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.
