A multi-GHz chaotic optoelectronic oscillator based on laser terminal voltage

“…It is notable that certain applications [14] of chaotic laser dynamics, and in particular chaotic radar [15] and ultrahigh-rate random-bit generation [16][17][18], do not intrinsically make use of the chaotic optical signal, but of an electrical signal detected by one or more PDs. These comments also apply for the work cited above on the generation of periodic microwave signals: a PD separate from the LD is always necessary to create an electrical signal while the optical signal itself is often not used directly [unless low-loss optical transmission of the signal is needed prior to optical-to-electrical (O/E) conversion].…”

Celebrating the laser

“…On the same theme, it should not be forgotten that Nature Photonics has already published two papers that describe the use of chaotically driven semiconductor lasers for generating high-quality random bit sequences of up to 300 Gbit s -1 for improved security in cryptography systems 3,4 .…”
