我们提出了一种新的直接空时脉冲整形器，工作在1.5-/spl μ/m的光通信波段，使连续光脉冲序列的产生在/spl sim/100 GHz的速率。该装置包括几个新颖的特征，例如使用衍射光学元件进行空间图案化，光纤耦合输入/输出，以及望远镜配置，它们共同使得能够在超过100 ps的时间孔径上产生几乎相等幅度的光脉冲序列。我们还提出了我们的设备的时间和频率调制行为的数学描述，除了在我们的系统中产生的连续100 GHz的光脉冲序列。
We present a novel direct space-to-time pulse shaper, operating in the 1.5-/spl mu/m optical communications band which enables generation of continuous optical pulse sequences at a rate of /spl sim/100 GHz. The apparatus includes several novel features, such as the use of a diffractive optical element for spatial patterning, fiber coupled input/output, and a telescopic configuration which collectively enable generation of nearly equal amplitude optical pulse sequences over a time aperture in excess of 100 ps. We also present a mathematical description of the temporal and frequency modulation behavior of our apparatus, in addition to continuous 100-GHz optical pulse sequences generated in our system.
