Free-space digital optical systems have demonstrated the capability to provide thousands of optical connections between optoelectronic chips. This dense concentration of channels creates substantial challenges in monitoring individual connections for diagnostic purposes without compromising performance. Prom the concept of stroboscopic techniques, we have designed and constructed a multichannel optical diagnostic tool that operates analogously to an electronic-sampling oscilloscope. The tool is economically constructed by the use of commercially available video cameras and video-enhanced personal computers. An integrated software application operates the tool and displays multiple-channel waveforms. We demonstrate the oscilloscope-sampling optical waveforms of a two-dimensional optoelectronic modulator array operating at data rates from 0.5 to 4 Gbits/s.
自由空间数字光学系统已展现出在光电子芯片之间提供数千个光连接的能力。如此密集的信道集中在不影响性能的前提下,为诊断目的监测单个连接带来了巨大挑战。基于频闪技术的概念,我们设计并构建了一种多通道光学诊断工具,其工作方式类似于电子采样示波器。该工具通过使用市售摄像机和视频增强型个人计算机经济地构建而成。一个集成软件应用程序操作该工具并显示多通道波形。我们展示了二维光电子调制器阵列在0.5至4 Gbit/s数据速率下的示波器采样光学波形。
