摘　　要：We experimentally developed massive parallel chaotic sources for random bit generation, based on a monolithically integrated amplified-feedback laser(AFL) array using the reconstruction-equivalent chirp technique. Proof-of-concept experiments demonstrate that using our method, eight independent random bit streams with 100 GSa/s and uniform wavelength spacing could be obtained. In addition, there is a low correlation between different bit-stream channels. Our approach enables scalable integration for large-scale parallel chaotic channels, potentially achieving throughput capacities of up to Tb/s for random bit generation.
