【摘要】 提出了一种利用单光源光电振荡器(OEO)结构实现多波长光脉冲输出的方案。通过一个直调光源和光谱切片技术在OEO腔内可以产生不同中心波长的光脉冲和电时钟信号。腔内多个波长通道自然形成的多环路结构可以有效地抑制信号边模。在5 GHz频率的实验演示中,该系统产生了脉宽约10 ps,抖动1 ps的单波长脉冲、20 GHz(4×5 GHz)的时分复用脉冲与波/时分复用脉冲。所得到电时钟信号的相位噪声在频偏10 kHz处为-113 dBc/Hz,边模抑制比为100 dBc/Hz。更多还原

【Abstract】 A scheme of generating multi-wavelength optical pulses based single light source optoelectronic oscillator (OEO)is proposed.By utilizing a directly modulated laser and spectral slicing technique,multi-wavelength optical pulses and electrical clock signal are generated in an OEO cavity.Multi-wavelength channels form a multi-loop configuration naturally,which can effectively suppress sidemodes.In demonstration,10-ps-wide optical ’pulses at 5 GHz repetition rate are generated with 1 ps timing jitter,which can be arranged in 20 GHz(4×5 GHz)OTDM and time-/wavelength-interleaved optical pulse stream at different nodes.Along with the optical outputs,5 GHz electrical signal with low phase noise(— 113 dBc/Hz at 10 kHz offset from the carrier)and — 100 dBc/Hz spurious modes suppression is also obtained.更多还原
