论文摘要
我们通过同时在KM-LONG BIOMODAL和6-LP-MODOMODE和6-LP-MODED级分级级别的几个模板纤维中，通过模式内多个四波混合和模式间跨相调制，在电信波长上报告了在电信波长处的实验生成的实验生成。更准确地说，首先通过模式内多个四波混合过程将初始注入基本模式注入基本模式的脉冲首先被非线性地压缩到分离良好的脉冲中，而几个匹配的连续波探针信号匹配的连续探针信号以这种方式将类似的脉冲曲线注入了类似的脉冲曲线，以相互作用与一个相互互动。具体而言，通过同时激发了6-LP模式纤维的三个高阶模式（LP11，LP02和LP31），沿群速度匹配的波长具有基本模式，四种空间多发性的40-GHz picsocecond脉冲传输是在可忽略的，具有可忽略的交叉角之间的，这些脉冲是在所有模式之间均可构成的。
We report on the experimental generation of spatially multiplexed picosecond 40-GHz pulse trains at telecommunication wavelengths by simultaneous intra-modal multiple four wave mixing and intermodal cross-phase modulation in km-long bi-modal and 6-LP-mode graded-index few-mode fibers. More precisely, an initial beat-signal injected into the fundamental mode is first nonlinearly compressed into well-separated pulses by means of an intra-modal multiple four-wave mixing process, while several group-velocity matched continuous-wave probe signals are injected into higher-order modes in such a way to develop similar pulsed profile thanks to an intermodal cross-phase modulation interaction. Specifically, by simultaneously exciting three higher-order modes (LP11, LP02 and LP31) of a 6-LP-mode fiber along group-velocity matched wavelengths with the fundamental mode, four spatially multiplexed 40-GHz picosecond pulse-trains are generated at selective wavelengths with negligible cross-talks between all the modes.
