“…By comparing to Refs. [25], [26], [27], [28], it is clearly shown from the figure that the TDS is successfully suppressed in our new configuration. It is noticed from the figure that the sidelobe base is slightly thicker than that of Fig.…”

“…In the engineering application point of view, our new random feedback scheme which allows vanishing the time-delay signature is promising in the engineering applications such as enhancing the randomness in random number generation or the security in secure chaos communications. Compared to the other works which uses post-signal processing [25], [26], [27], [28], our configuration is the first configuration of random feedback which allows generating complex signals directly without the presence of the time-delay signature, not suppressing it by any post-signal processing. It can also be used for sensing application as in sensing application with chaotic lasers.…”

“…In order to enhance the security or the randomness of number generation, the TDS must be suppressed from chaotic signals. Some studies have shown that the TDS can be suppressed using post-signal processing such as self-interference [25], SBS [26], [27] or optical time-lens [28]. However, there is no optical feedback configuration to generate directly TDS-free signals from a laser diode.…”

“…As an example, for ultra-fast optical random number generation [43][44][45], it is crucial to generate optical chaotic signals that are as uncorrelated and as "pseudorandom" as possible, for which its deterministic nature is hidden by noise-like properties. Many different setups have been proposed to generate such broad-band, high-entropy optical signals [46][47][48][49][50]. Our algorithm allows an automatic comparison of the strength of the correlations and the level of randomness of signals generated by different setups.…”

Time series analysis comprises a wide repertoire of methods for extracting information from data sets. Despite great advances in time series analysis, identifying and quantifying the strength of nonlinear temporal correlations remain a challenge. We have recently proposed a new method based on training a machine learning algorithm to predict the temporal correlation parameter, α, of flicker noise (FN) time series. The algorithm is trained using as input features the probabilities of ordinal patterns computed from FN time series, xαFN(t), generated with different values of α. Then, the ordinal probabilities computed from the time series of interest, x(t), are used as input features to the trained algorithm and that returns a value, αe, that contains meaningful information about the temporal correlations present in x(t). We have also shown that the difference, Ω, of the permutation entropy (PE) of the time series of interest, x(t), and the PE of a FN time series generated with α=αe, xαeFN(t), allows the identification of the underlying determinism in x(t). Here, we apply our methodology to different datasets and analyze how αe and Ω correlate with well-known quantifiers of chaos and complexity. We also discuss the limitations for identifying determinism in highly chaotic time series and in periodic time series contaminated by noise. The open source algorithm is available on Github.

“…65 In addition, the identification methods of the TDS also include delayed mutual information 66 and permutation entropy 67 in the time domain, and the spectrum identification method 68 in the frequency domain. In order to suppress the TDS of a chaotic signal, scholars have carried out extensive researches, including fiber grating feedback, [69][70][71][72] fiber dispersion effect, [73][74][75] fiber backscattering effect, 76,77 external optical injection, [78][79][80] and other.
