We describe an optoelectronic system for simultaneously generating parallel, independent streams of random bits using spectrally separated noise signals obtained from a single optical source. Using a pair of nonoverlapping spectral filters and a fiber-coupled superluminescent LED (SLED), we produced two independent 10 Gb/s random bit streams, for a cumulative generation rate of 20 Gb/s. The system relies principally on chip-based optoelectronic components that could be integrated in a compact, economical package.
我们描述了一种光电系统,该系统使用从单个光源获得的光谱分离噪声信号来同时生成并行、独立的随机位流。我们使用一对不重叠的光谱滤波器和光纤耦合的超辐射发光二极管(SLED),产生了两个独立的 10Gb/s 随机位流,累积生成速率为 20Gb/s。该系统主要依赖于可以集成在紧凑、经济的封装中的基于芯片的光电组件。
