テルライトガラス融液を2本のシリカガラス製光ファイバの端面間に固着して得 た素子の光透過・反射特性を調べた。前者の熱膨張率が2桁大きいにもかかわら ず、冷却時の収縮による破損や気泡の無い良好な構造を得ることができた。この 素子はテルライトガラス部において導波構造を持たないた...

Fluorescence lifetime of Er3+ was measured for F-doped tellurite glasses with parallel heat treatment under a temperature gradient atmosp...

Less than 1.5dB of insertion loss was realized in an optical coupling structure in which two TEC (Thermal-diffusion Expanded Core) fibers...

Several nano liters of tellurite glass melt was inserted and quenched between two ends of silica glass optical fibers to form a optical ...

Several nano liters of tellurite glass melt (xTeO2 - (100 - x)ZnO, x = 80,90,100 in mol%) were inserted and quenched between tow ends of ...
