摘要	A grating (461) assisted coupling of a semiconductor waveguide to a dielectric waveguide (451) is provided with one or more reflective stacks (330, 332, 334) to enhance the coupling efficiency. The glass or dielectric core (458) may be efficiently butt-coupled to the core of an optical fiber (470). A laser and semiconductor waveguide, reflective stacks coupling grating, and dielectric waveguide are integrated on a single substrate. Further, multiple lasers (410, 420, 430, 440) with differing lasing frequencies may be integrated and their outputs grating coupled into a single dielectric waveguide (450) for wavelength division multiplexing.
其他摘要	光栅（461）辅助半导体波导与电介质波导（451）的耦合设置有一个或多个反射堆叠（330,332,334），以提高耦合效率。玻璃或介电芯（458）可以有效地对接耦合到光纤（470）的芯。激光和半导体波导，反射堆叠耦合光栅和介电波导集成在单个衬底上。此外，可以集成具有不同激光频率的多个激光器（410,420,430,440），并且它们的输出光栅耦合到单个电介质波导（450）中以进行波分复用。
主权项	A coupler between a semiconductor waveguide and a dielectric waveguide, comprising: (a) a grating between said semiconductor waveguide and said dielectric waveguide; and (b) at least two reflective stacks adjacent said semiconductor and said dielectric waveguides wherein each reflective stack is configured to reflect power lost to the substrate from a leaky mode of the grating into the dielectric waveguide.
