## Description

- description: |
    Less than 1.5dB of insertion loss was realized in an optical coupling
    structure in which two TEC (Thermal-diffusion Expanded Core) fibers are
    spliced via quenched TeO2 melt whose length was 0.5mm.  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.
