Phase space techniques for steering laser transients

New Role for Nonlinear Dynamics and Chaos in Integrated Semiconductor Laser Technology

“…The resulting nonlinear dynamics are undesired features for many applications since they hamper the (cw and modulation) performance of the laser. So far, this has received not much attention from the technical community, with one notable exception, i.e., the work by Lippi et al on enhancement of the modulation bandwidth by phase-space steering [8][9][10]. Current (binary) optical telecommunications technologies are focused on the mitigation of the nonlinear dynamics and the enhancement of ''stable'' behavior.…”

“…It is known that the dynamics arise due to the interplay of different time scales. It is known that the dynamics arise due to the interplay and research into phenomena as low frequency fluctuations (LFF) in semiconductor lasers with external feedback and the study of the dynamics of semiconductor lasers with optical injection [7] has helped to mature this scientific field so much that applications can now be made [8,10,12].…”

“…[15,17]. These quantities provide essential information for the exploitation of the PIC dynamics in applications such as chaotic encryption [12], phase-space steering [8][9][10], interferometric distance measurements, and broadband light sources. On the basis of the fingerprints of the CPMLL, it was even possible to identify the values of the control parameters to make the device operate as it was originally intended.…”

High-Speed Switch-On of a Semiconductor Gas Discharge Image Converter Using Optimal Control Methods

“…Many applications, e.g., pulse lasers in technology and optical communication, require a stable and controllable operation of devices. Lippi et al [10][11][12] have suggested a method for controlling gas discharge CO 2 and semiconductor lasers to suppress oscillations in the emitted power of transient modes and to shorten the time lag in a pulse. To reach these goals, they use a simplified dynamical model for the considered laser, namely, a two-component Lotka-Volterra system.…”

“…The feeding voltage is taken as the control function. The basic idea of our research is closely related to the work of Lippi et al [10][11][12], in which steering schemes of a gas discharge pulse CO 2 laser which improve the transient time dramatically are developed. Although these control strategies are not derived on the basis of optimal control theory, they expose some characteristic features of optimal bang-bang controls.…”
