摘要: A novel time-domain ultrafast optical pulse shaping approach using long-period fiber gratings (LPGs) is proposed. The technique based on exploiting a superluminal space-to-time mapping effect in weak-coupling LPGs and it enables the synthesis of arbitrary complex waveforms with femtosecond features feasible simple LPG profiles, e.g., spatial grating-apodization resolutions above millimeter range. numerically demonstrated by generation multi-Tsymbol/s serial data streams under coding (e.g., QPSK 16-QAM) formats.
