Abstract
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 random bit streams, for a cumulative generation rate of . The system relies principally on chip-based optoelectronic components that could be integrated in a compact, economical package.
