唐明, 霍亮 摘要：基于自研高性能多芯光纤（MCF）及器件，结合可编程拉锥处理技术，提出并实现级联式和并联式无限冲激响应微波光子滤波器（IIR-MPF），Q值分别达到143和136。基于MCF和长周期光栅（LPG）在波长和空间两个维度分别实现可重构的有限冲激响应微波光子滤波器（FIR-MPF），完成了3种两抽头滤波器的切换。此外，将MCF-LPG和定向弯曲系统应用于空分复用相干光传输系统中，实现可重构的芯间信号切换。实验结果表明该方案具有高达39 dB的切换消光比，传输总容量达1.344 Tbit/s。

Abstract： Based on self-developed high-performance multicore fiber (MCF) and devices, combined with programmable tapering technique, cascaded and parallel infinite impulse response microwave photonic filters (IIR-MPFs) are proposed, with Q values of 143 and 136, respectively. Based on the MCF and long-period gratings (LPG), the reconfigurable finite impulse response microwave photon filter (FIR-MPF) is implemented in two dimensions of wavelength and space respectively, and three different two-tap filters are realized. In addition, MCF-LPG and a directional bending system are used in a space division multiplexing coherent transmission system to realize reconfigurable inter-core signal switching. The experimental results show that the scheme has a switching extinction ratio of up to 39 dB and the total transmission capacity is 1.344 Tbit/s.
