| 摘要 |
This optical member guides light from a first optical waveguide to a second optical waveguide, and is positioned between the first optical waveguide and the second optical waveguide. The optical member has a substrate, a lens, and a coating layer. The lens is formed of an energy-curable resin having a linear expansion coefficient of 70ppm or less, and is positioned on the substrate. The coating layer is formed so as to cover the lens, and prevents the reflection of light. |
