提出了一种用于光纤与薄半导体波导耦合的新型双光栅辅助定向耦合器（DGADC）。作为一个例子，DGADC在绝缘体上硅进行了讨论。使用这种耦合器可以获得超过90%的最大耦合效率，而以前报道的最高耦合效率仅为40%。
A novel dual grating-assisted directional coupler (DGADC) for coupling an optical fiber with a thin semiconductor waveguide is proposed. As an example, a DGADC in silicon-on-insulator is discussed. Maximum coupling efficiency in excess of 90% can be obtained using this coupler, while the highest coupling efficiency previously reported was only 40%.
