设计了一种用于SOI波导与光纤耦合的高效率宽带光栅耦合器。光栅只有13微米长和12微米宽，和凹槽的尺寸进行了优化数值。对于TE偏振，当使用具有两对底部反射器的SOI时，在35 nm波长范围内与单模光纤的耦合损耗低于1 dB。还计算了制造误差的容限。(C)2004年美国光学学会。
We have designed a high-efficiency broadband grating coupler for coupling between silicon-on-insulator (SOI) waveguides and optical fibers. The grating is only 13 mum long and 12 mum wide, and the size of the grooves is optimized numerically. For TE polarization the coupling loss to single-mode fiber is below 1 dB over a 35-nm wavelength range when using SOI with a two-pair bottom reflector. The tolerances to fabrication errors are also calculated. (C) 2004 Optical Society of America.
