摘要：

We propose a power spectrum analysis method to directly identify the time delay of a chaotic semiconductorlaser with optical feedback. By measuring the radio frequency (RF) power spectrum of the chaotic laserand performing an inverse Fourier transform, we can easily unveil all the time delay signatures, regardless ofwhether the chaotic output is induced by single or multiple feedback. This method successfully retrieves thetwo time delay signatures from the power spectrum of a semiconductor laser with double-cavity feedback.
