多模干涉仪是提高未来探测系统数据传输能力的关键部件。我们提出了两种传统的高性能mmi，在250nm SOI平台上制造，具有不同的功率分割比，分别作为50%:50%的功率分割器用于马赫-曾德尔调制器，86%:14%的功率分割器用于未来收发器设计的环路控制。此外，我们还提出了基于亚波长光栅的新型mmi。通过对相关部件折射率的工程化设计，使更紧凑的50%:50% mmi和多端口、低相位误差的mmi成为可能。
Multimode interferometers (MMIs) are key components for high-bandwidth transceivers in upgrading the data transmission of future detector systems. We present two conventional highperformance MMIs fabricated on a 250 nm SOI platform with different power splitting ratios which operate as 50%:50% power splitter for Mach-Zehnder modulators and as 86%:14% power splitter for loop control in future transceiver designs, respectively. Besides, we present the novel MMIs based on sub-wavelength gratings. By engineering the refractive index of relevant parts, more compact 50%:50% MMIs and multi-port, low phase error MMIs become feasible.
