Summary:
The optical frequency dynamics in chaotic laser outputs has been extracted from the laser intensity of low frequency fluctuations using optical heterodyne detection. We experimentally investigate the extraction of chaotic frequency dynamics at fast oscillations over GHz. We compare the characteristics of optical frequency dynamics with optical intensity dynamics. We use the optical frequency dynamics to perform fast physical random number generation.
