设计了一种基于布拉格光栅辅助多模干涉（MMI）耦合器的硅三工器，并进行了实验验证。与传统的基于MMI的三工器相比，器件长度不需要是不同波长拍长的公倍数。用三维时域有限差分法对1310 nm波段进行了模拟，带宽超过100 nm。制作的片上三工器的实验结果表明，消光比高于15 dB和插入损耗约1 dB的所有输出端口。该器件的总尺寸仅为5.4 × 453 μm2，是目前已报道的三工器中尺寸最小的。
A silicon triplexer based on Bragg grating-assisted multimode interference (MMI) couplers is designed and experimentally demonstrated. Compared with the conventional MMI-based triplexers, the device length is not required to be the common multiple of beat length of different wavelengths. The simulated bandwidth is over 100 nm for 1310-nm band with the 3-D finite-different time-domain method. Experimental results of the fabricated on-chip triplexer show extinction ratios higher than 15 dB and insertion losses around 1 dB in all output ports. The total device size is only 5.4 × 453 μm2, which is the smallest size over the experimentally demonstrated triplexers ever reported.
