我们目前，据我们所知，第一个实验演示的可重构全光片上多输入多输出三模解复用的基础上多平面光转换。该解复用器由集成在一个紧凑的硅芯片上的级联移相器阵列和多模干涉耦合器组成。通过优化移相器，实验实现了可重构三模解复用，在23 nm光带宽上，波长相关损耗小于3 dB，模式串扰小于-10 dB。最后给出了40 Gbps非归零信号的无差错模式解复用。
We present, to the best of our knowledge, the first experimental demonstration of reconfigurable all-optical on-chip multi-input-multi-output three-mode demultiplexing based on multi-plane light conversion. The demultiplexer consists of cascaded phase shifter arrays and multimode interference couplers integrated on a compact silicon chip. By optimizing the phase shifters, reconfigurable three-mode demultiplexing is experimentally realized with wavelength-dependent loss of less than 3 dB and modal crosstalk of less than -10 dB over a 23 nm optical bandwidth. Error-free mode demultiplexing of 40 Gbps non-return-to-zero signal is also demonstrated.
