摘要	A semiconductor photonic device includes a substrate, facet(s), and optical coupler(s) associated with the facet(s). Each optical coupler can couple an electromagnetic field incident on the respective facet towards the substrate as the electromagnetic field proceeds into the semiconductor photonic device. In some examples, each coupler has waveguides extending in a longitudinal direction and at least partly encapsulated within corresponding cladding layers. A first waveguide extends farther from the facet in the longitudinal direction than does a second waveguide. The second waveguide is located farther above the silicon substrate than is the first waveguide. The coupler can include a stack of waveguide assemblies. A lower waveguide assembly can include one waveguide. An intermediate or upper waveguide assembly can include multiple waveguides. In some examples, at least one waveguide tapers along its length.
其他摘要	半导体光子器件包括衬底，小平面和与小平面相关联的光耦合器。随着电磁场进入半导体光子器件，每个光耦合器可以将入射在相应小面上的电磁场耦合到衬底。在一些示例中，每个耦合器具有在纵向方向上延伸并且至少部分封装在相应覆层内的波导。与第二波导相比，第一波导在纵向方向上远离小面延伸。第二波导比第一波导更位于硅衬底之上。耦合器可以包括一叠波导组件。下波导组件可以包括一个波导。中间或上部波导组件可以包括多个波导。在一些示例中，至少一个波导沿其长度逐渐变细。
