中文摘要	针对光电混合模数转换系统中采样光脉冲很窄,高速积分保持电路实现较困难这一问题,本文提出了一种新型的高速光保持模块.通过使用多个耦合器组成的无源结构,将采样后的超窄光脉冲转换成一族脉冲簇,再经过光电转换和电低通滤波,得到了顶部较平、脉宽较宽的脉冲,有助于降低后续处理电路的复杂度.实验结果表明,这种结构能够较好地实现将超窄脉冲展宽成平顶宽脉冲的功能.; In an optoelectronic hybrid analog-to-digital conversion system,the duration of the optical sampling pulses was so short that high-speed "integrate-hold" electrical circuits were comparatively difficult to realize.In order to deal with this problem,a novel high-speed "Optical Hold Module" was proposed in this paper.By using a passive structure that consists of multiple optical couplers,the post-sampling ultra-short optical pulses were converted to pulse clusters,which were further converted to broader pulses with a relatively flat top after photo-electrical conversion and electrical low-pass filtering.This was helpful to reduce the complexity of the following electrical processing.The experiment shows that this structure was capable of converting the ultra-short pulses to broader pulses with flat top.; 国家自然科学基金(60477021); 国家自然科学基金(60607008)资助
