摘要

具有可重构功能的模式转换器对于在基于现代模分复用（MDM）技术的光网络中实现灵活运行至关重要。本文提出了一种新型可重构三模式转换器，能够将 TE0、TE1 和 TE2 模式转换为任何所需的输出模式，如 TE0、TE1 或 TE2，用于 MDM 光通信系统。我们的设备利用热光学（TO）效应，由级联 Y 型结和马赫-泽恩德干涉仪（MZI）组成，包括两个三臂模式转换器和一个双臂模式转换器。对我们的设备进行的分析和数值验证证明了它的高效运行，测量结果与模拟性能十分吻合。我们的光子集成电路 (PIC) 兼容型器件在整个 C 波段（1.530-1.565 μm）的模式转换效率 (MCE) 超过 92.5%，最大插入损耗 (IL) 为 8.3 dB，串扰 (XT) 低于 -18.9 dB。我们的三模式高能效、偏振不敏感转换器在提高 MDM 光网络的灵活性方面具有巨大潜力，因此是未来开发和部署的可行候选方案。

Reconfigurable Three-Mode Converter for Flexible Mode Division Multiplexing Optical Networks

Mode converters with reconfigurable functionality are essential for enabling flexible operation in modern mode division multiplexing (MDM) technology-based optical networks. In this paper, we propose a novel reconfigurable three-mode converter capable of converting the TE ₀ , TE ₁ , and TE ₂ modes to any desired output mode, such as TE ₀ , TE ₁ , or TE ₂ , for use in MDM optical communication system. Our device utilizes thermo-optic (TO) effects and consists of cascaded Y-junctions and Mach-Zehnder interferometers (MZIs), comprising two three-arm mode converters and one two-arm mode converter. The analytical and numerical verification of our device demonstrates its efficient operation, and the measurement results align favorably with the simulated performance. Our photonic integrated circuit (PIC) compatible fabricated device exhibits the mode conversion efficiency (MCE) of higher than 92.5% with maximum insertion loss (IL) of 8.3 dB and crosstalks (XTs) lower than −18.9 dB in the entire C band (1.530-1.565 μm). Our three-mode energy efficient and polarization-insensitive converter offers promising potential in enhancing the flexibility of MDM optical networks, making it a viable candidate for future development and deployment.
