Summary:
Employing the Lang-Kobayashi equations, we numerically studied random bit generation in cases of short passive waveguides. The generated random bit sequences are evaluated by using the statistical tests of randomness provided by NIST. We found that by controlling the injection current and the amount of the optical feedback, highly chaotic oscillations fast and random enough to pass all of the NIST tests can be obtained even if the lengths of the passive waveguides are much shorter than 1cm.
