Hg. Kim et al., FIBER DRAWING OF LINBO3-DOPED MIXED-ALKALI TELLURITE GLASSES, Nippon Seramikkusu Kyokai gakujutsu ronbunshi, 103(10), 1995, pp. 1073-1076
A transparent mixed alkali tellurite glass of 10Li(2)O-10Na(2)O-80TeO(
2) containing LiNbO3 crystals with a diameter of about 4 mu m and with
the amount of about 6 mass% is prepared using an incorporation method
, and LiNbO3-doped tellurite glass fibers are drawn. LiNbO3 particles
in the fiber and bulk samples are well dispersed. The samples also hav
e a good transparency. The mixed alkali tellurite glass with a high th
ermal stability against crystallization and with a high refractive ind
ex of n = 1.98 is very suitable for incorporation of LiNbO3 crystals a
nd for LiNbO3-doped fiber drawing. This technique will be applicable f
or fabrications of nonlinear optical glass fibers containing various n
onlinear optical crystals.
