“…The previous theoretical analysis motivates the use of our polarization chaos as a physical source for a non-deterministic and rapidly varying entropy. But similarly to previous experimental realizations of chaos-based RNG [7,9,[11][12][13][14][15][16][17], a suitable post-processing must be implemented to first overcome the weaknesses of the entropy source, in particular to remove the bias in the sequence of zeros and ones, and secondly to possibly increase the random bit rate. As already reported [20], using one threshold to generate random sequences is quite challenging as it needs to be precisely set and readjusted to avoid long-term bias.…”

We demonstrate the physical generation of random bits at high bit rates (> 100 Gb/s) using optical chaos from a solitary laser diode and therefore without the complex addition of either external optical feedback or injection. This striking result is obtained despite the low dimension and relatively small bandwidth of the laser chaos, i.e. two characteristics that have been so far considered as limiting the performances of optical chaos-based applications. We unambiguously attribute the successful randomness at high speed to the physics of the laser chaotic polarization dynamics and the resulting growth rate of the dynamical entropy.

“…For these reasons, we set our goal to study a system without equilibrium points that could present these interesting properties. The first property is bistability which is a very important feature of nonlinear systems [4,13,19,40,46] because they have potential engineering applications such as modelling memory in neural network [56,3,26] or random bit generation [34]. The second feature is antimonotonicity phenomena which arises where periodic orbits are created and destroyed as a control parameter is varied.…”

This paper investigates numerically and experimentally an electronic circuit modelling the dynamics of a system without equilibrium point recently introduced by Shahzad et al. (Eur Phys J Spec Top 224:1637-1652, 2015). By varying the parameters of the electronic circuit, new behaviors are found including antimonotonicity, chaotic bistable hidden attractors, chaotic bubble hidden attractors, offset boosting and partial amplitude control. Another outcome of this paper is the forward and reversed interior crisis features found in a chaotic circuit without equilibrium point. Laboratory experiments and PSIM simulations are carried out to confirm results predicted by numerical simulations.

“…The low-and high-frequency oscillations used for clock recovery have been intensively studied in the past ten years [5]- [10]. Recently, the chaotic feature of MISL has attracted significant attention due to their deterministic nature, broadband and noise-like spectral distribution, which are very attractive in high speed random bit generation [11], [12], chaos synchronization communication [13]- [17], and precision ranging of lidar systems [18]- [20].…”

The dynamics of monolithically integrated amplified feedback lasers (AFL) is investigated through numerical simulation and experimental verification. The period-doubling route to chaos and high-frequency microwave generation are demonstrated through simulation. Then, we design and fabricate monolithically integrated AFLs. Mappings of dynamic states and oscillation frequency in the parameter space of phase section current I P and amplifier section current I A are depicted. For relative small I A , the period doubling evolution to chaos is presented with the increase of I P . For the relative large I A , a high-frequency mode-beating (M-B) pulsation can be observed under suitable value of I P . The oscillation frequency of period-one is about 10 GHz and the frequency of M-B pulsation is over 40 GHz for the device with a total length of 780 μm.
