A low-cost and high-performance wavelength division (de)multiplexing structure in the mid-IR wavelength range is demonstrated on the silicon-on-insulator platform using an interleaved angled multimode interferometer (AMMI). As compared to a single AMMI, the channel count was doubled and the channel spacing halved with negligible extra insertion loss and crosstalk and with only a slight increase in device footprint. The device requires only single lithography and etching steps for fabrication. Potential is also shown for achieving improved performance with further optimized design.
在绝缘体上硅平台上，利用交错角多模干涉仪（AMMI）展示了一种低成本、高性能的中红外波长范围内的波分复用（解复用）结构。与单个AMMI相比，通道数增加了一倍，通道间距减半，额外的插入损耗和串扰可忽略不计，且器件占用面积仅略有增加。该器件制造仅需单个光刻和蚀刻步骤。进一步优化设计还显示出实现性能提升的潜力。
