可重构单一光学模式转换器可以将多个正交空间模式转换为不同的正交模式，而没有基本光学损耗，这对于模分复用（MDM）光通信、成像和量子计算非常重要。在这封信中，我们提出了一种新型集成可重构单一光模式转换器，它由级联多模干涉耦合器和移相器阵列组成。我们通过数值研究了其实现任意单一模式转换的能力，并证明了其在 MDM 传输系统中模式解扰和模式切换的适用性。
Reconfigurable unitary optical mode converters that can convert multiple orthogonal spatial modes into different orthogonal modes without fundamental optical loss are important for mode-division-multiplexed (MDM) optical communication, imaging, and quantum computation. In this letter, we propose a novel integrated reconfigurable unitary optical mode converter, which consists of cascaded multimode interference couplers and phase shifter arrays. We numerically investigate its ability to realize arbitrary unitary mode conversion and demonstrate its applicability to mode unscrambling as well as mode switching in MDM transmission systems.
