“…[2]. In integrated lasers, problems with reproduction may show up as unexpected dynamics of the output field, quite often referred to as unstable behavior or just noise [3,4]. However, it is the aim of this Letter to demonstrate that the output dynamics of the integrated optical devices which we have experimentally investigated are well behaving, well understandable, and well classifiable in terms of nonlinear dynamics.…”

“…Such a configuration, consisting of a long amplifier section with a short absorber in the center, is designed to produce a train of picosecond optical pulses, but in practice the intended dynamics are hard to achieve. Instead, a variety of other dynamics may be observed, depending on the precise settings of the external control parameters, in this case the bias current and the absorber voltage [3,4]. The measurement setup is depicted in Fig.…”

“…Built-on-chip chaotic emitters through photonic integration appear very attractive, since they could be easily included in the existing infrastructure of optical networks. Although a few works in the near past presented photonic devices that exhibited interesting nonlinear and chaotic behavior, their low-complexity and narrow-bandwidth emitted signals made them inappropriate for high bit rate data encryption applications [16][17][18][19]. On the contrary, a controllable photonic integrated emitter has been presented in [20], where preliminary results proved the feasibility of this device to exhibit complex chaotic dynamics under strictly determined operating conditions.…”

Security in information exchange plays a central role in the deployment of modern communication systems. Besides algorithms, chaos is exploited as a real-time high-speed data encryption technique which enhances the security at the hardware level of optical networks. In this work, compact, fully controllable and stably operating monolithic photonic integrated circuits (PICs) that generate broadband chaotic optical signals are incorporated in chaos-encoded optical transmission systems. Data sequences with rates up to 2.5 Gb/s with small amplitudes are completely encrypted within these chaotic carriers. Only authorized counterparts, supplied with identical chaos generating PICs that are able to synchronize and reproduce the same carriers, can benefit from data exchange with bit-rates up to 2.5Gb/s with error rates below 10(-12). Eavesdroppers with access to the communication link experience a 0.5 probability to detect correctly each bit by direct signal detection, while eavesdroppers supplied with even slightly unmatched hardware receivers are restricted to data extraction error rates well above 10(-3).

“…In [12] monolithic colliding-pulse modelocked lasers exhibited nonlinear behavior, from cw operation to self-pulsations and mode-locking, for the full range of the control parameters. In [13] a semiconductor laser, followed by a phase section and an active feedback element, forms a very short complex photonic circuit that provides several types of dynamics and bifurcations under optical feedback strength and phase control.…”

A novel photonic monolithic integrated device consisting of a distributed feedback laser, a passive resonator, and active elements that control the optical feedback properties has been designed, fabricated, and evaluated as a compact potential chaotic emitter in optical communications. Under diverse operating parameters, the device behaves in different modes providing stable solutions, periodic states, and broadband chaotic dynamics. Chaos data analysis is performed in order to quantify the complexity and chaoticity of the experimental reconstructed attractors by applying nonlinear noise filtering.
