Fast True Random Bit Generation With an SOA-Based Random Fiber Laser

Physical random bits are generated at rates up to 40 Gbps using an 8-bits digital oscilloscope acquiring the optical intensity at the output of an SOA-based random fiber laser. The simple and minimal off-line post-processing (the selection of 4 LBS) can be easily implemented in real time. The true random bits sequences passed all NIST tests.
