介绍了我们在任意形状毫米波电磁波形的光学产生方面所做的工作。通过一种新的技术，利用来自直接空时脉冲整形器的定制的光脉冲序列来驱动高速光电转换器，我们产生了中心频率接近50 GHz的幅度均衡、任意相位和频率调制的波形。此外，通过对脉冲整形器输出的色散展宽，我们还展示了该技术的扩展，以产生低千兆赫兹范围内的任意电磁波形。在分散拉伸的配置中，我们的电波形的持续时间是通过脉冲整形设备中简单的对准改变来调节的。
We present our work in optical generation of arbitrarily shaped millimeter-wave electromagnetic waveforms. Through a novel technique, which utilizes tailored optical pulse sequences from a direct space-to-time pulse shaper to drive a high-speed optical-to-electrical converter, we generate amplitude-equalized, arbitrarily phase- and frequency-modulated waveforms at center frequencies approaching 50 GHz. In addition, we demonstrate the extension of this technique to generation of arbitrary electromagnetic waveforms in the low-gigahertz range, through dispersive stretching of the pulse shaper output. In the dispersively stretched configuration, the duration of our electrical waveforms is tuned through simple alignment changes in our pulse-shaping apparatus.
