作者提出了一种新型 2 × 2 多模干扰 (MMI) 耦合器，可提供任意功率分配比。所提出的耦合器在其 MMI 区域的中心有一个包层填充的间隙。使用基于二氧化硅的平面光波电路制造的耦合器表现出 0-100% 的分光比，超额损耗 < 1 dB。
The authors propose a novel 2 × 2 multimode interference (MMI) coupler that provides an arbitrary power splitting ratio. The proposed coupler has a cladding-filled gap in the centre of its MMI region. Couplers fabricated using a silica-based planar lightwave circuit exhibited splitting ratios from 0–100% with excess losses < 1 dB.
