摘要

我们提出并实验证明了一种双向角度多模干涉仪(Bi-AMMI)用于交错波分复用应用。利用本征模展开法得到了2 × 4双ammi的光谱响应，包括多模波导同侧输入输出端口之间的交叉耦合。为了验证我们的设计，制作并测量了独立和交错的bi - ammi。Bi-AMMI的插入损耗为0.99 ~ 1.21 dB，不必要的交叉耦合低于- 20 dB。该器件的测量光损耗为4.77 ~ 5.02 dB，平均串扰为−18 dB。

Interleaved bidirectional angled multimode interferometer for wavelength division (de)multiplexings

We propose and experimentally demonstrate a bidirectional angled multimode interferometer (Bi-AMMI) for interleaved wavelength division multiplexing applications. The spectral response of the 2 × 4 Bi-AMMI is obtained using an eigenmode expansion method, including the cross coupling between the input and output ports at the same side of the multimode waveguide. To verify our design, both the standalone and interleaved Bi-AMMIs were fabricated and measured. The Bi-AMMI exhibits an insertion loss of 0.99 to 1.21 dB, and the unwanted cross coupling is lower than −20 dB. The interleaved device exhibits a measured optical loss of 4.77 to 5.02 dB, and the average crosstalk is calculated to be −18 dB.
