SPOT SIZE CONVERTER AND OPTICAL APPARATUS |
| 摘要 |
A spot size converter includes a first silicon waveguide core that includes a width-fixed region having a fixed width and a width-tapered region continuing to the width-fixed region and having a width reducing toward a terminal portion, and a second waveguide core continuing to the first silicon waveguide core and covering at least the width-tapered region. The first silicon waveguide core has a thickness-wise step in the width-fixed region. |
