    • Provided is a core which reduces optic splice loss between discontinuous optical waveguides. The core includes a first waveguide propagation portion having first light-receiving width, a first lightwave discontinuous portion having second light-receiving width, a first taper structure portion having both ends connected to the first lightwave propagation portion and to the first lightwave discontinuous portion, respectively and decreasing in light-receiving width as it goes from the first lightwave propagation portion to the first lightwave discontinuous portion, a second lightwave propagation portion having third light-receiving width, a second lightwave discontinuous portion having fourth light-receiving width, and a second taper structure portion having both ends connected to the second lightwave propagation portion and to the second lightwave discontinuous portion, respectively and decreasing in light-receiving width as it goes from the second lightwave propagation portion to the second lightwave discontinuous portion.
    • 提供了减少不连续光波导之间的光接头损耗的核心。 该芯包括具有第一光接收宽度的第一波导传播部分,具有第二光接收宽度的第一光波不连续部分,具有连接到第一光波传播部分的两端和第一光波不连续部分的第一锥形结构部分, 分别从第一光波传播部分到第一光波不连续部分的光接收宽度减小,具有第三受光宽度的第二光波传播部分,具有第四光接收宽度的第二光波不连续部分和 第二锥形结构部分,其两端分别连接到第二光波传播部分和第二光波不连续部分,并且随着从第二光波传播部分到第二光波不连续部分的光接收宽度的减小,第二锥形结构部分。
