“…In this region, the 'period' of the dynamics is typically much less stable than other regions in the map. Another technique used to identify unstable dynamics makes use of variation in the peak-to-peak amplitude of the output power time series 16 . A sliding window of approximately 625 ps (200pts) in length is passed over the full 100 ns (32017pts) normalized time series.…”

Optical injection is one of the key methods for invoking nonlinear dynamical outputs in laser systems. The system parameters that are used to control the nature of the output from such a system are the injection strength and the frequency detuning between the optical frequency of the free running master and slave lasers. A map of the dynamics can be generated using a number of measurands to facilitate identifying the fundamentally different dynamical regions in the injection-strength/frequency-detuning parameter space. Herein we describe a set of automated algorithms used to establish several measures to identify transients and instabilities in the nonlinear dynamical output of an optically injected vertical cavity surface emitting laser (VCSEL), for set and unchanging driving parameters.

“…As a consequence of that, monitoring and analyzing the nonlinear dynamical features is of first importance since it can enable insights for various engineering applications. The experimental extraction of the nonlinear dynamical features is not intensively studied as for instance described in references [7][8][9]. Most of the work is done theoretically but a very little is done experimentally.…”

We propose in this paper a self-referenced method based on asynchronous sampling to monitor the waveform of periodic and quasi-periodic signals, with a low number of samples, typically 2¹⁴ or lower. It provides a high-resolution representation of the signal under test, representative of the analog intensity signal under test. Additionally, the proposed approach is robust to the timing jitter of the signal, as experimentally demonstrated. Such features enable the accurate display of periodic and quasi-periodic signals. The method is applied to the characterization of laser dynamics, such as time series and phase portrait of periodic nonlinear regimes in optically injected lasers.

“…In vertical-cavity surface-emitting lasers (VCSELs) the polarization degree of freedom allows for an even wider variety of dynamical regimes, as the injected light can have either the same linear polarization as the free-running laser (this injection scheme has been referred to as parallel injection) or it can have the orthogonal polarization (referred to as orthogonal injection) [11][12][13][14][15][16].…”

We study numerically the output polarization of a vertical-cavity surface-emitting laser (VCSEL) subject to orthogonal optical injection. We focus on the width of the hysteresis cycle induced by the variation of the detuning of the injected light. For positive detuning and strong enough optical injection we find that the hysteresis width is proportional to the birefringence parameter; for negative detuning the hysteresis width is narrow and is unaffected by the injection strength. Our results are in good agreement with recent experimental observations.
