“…2, one outstanding feature is the increased damping rate of the transient. This agrees with experimental observations [44]. The output also appears to be more noisy, possibly owing to beating between the longitudinal modes.…”

A new, dynamic, time-domain, numerical model for external cavity lasers, based on the transmission-line laser model (TLLM), is introduced. This is able to show the evolution of spectra from large-signal modulated devices, even when the modulation pulsewidth is less than the external cavity round-trip delay. The model is demonstrated using short and long dispersionless cavities. Results in the time and spectral domains are in agreement with those of previous theoretical and experimental work.

“…In the case of long EC and moderate feedback rates, the stable emission of the SL is easily destabilized and chaotic regimes arise. Typically observed chaotic dynamics in the long cavity regime are the so-called low-frequency fluctuations (LFF) [16,17], which manifest as sporadic and sudden dropouts of the light intensity followed by successive, much slower stepwise return to maximal power. The regime of LFF anticipates another intriguing regime that is the coherence collapse (CC) regime [18].…”

We study the influence of delayed optical feedback from a short external cavity on the emission dynamics of semiconductor lasers using the Lang and Kobayashi rate equation model. A combination of numerical integration and continuation techniques allows us to bring new light into the bifurcation scenario leading to the regular pulse packages (RPP) regime. We give examples of bistability between RPP and time-periodic or steady state solutions. Our bifurcation study of RPP regime is complemented by an analysis of the dependency of the RPP period on the laser and feedback parameters. We qualitatively study this new dynamical regime by plotting a two-dimensional map in the feedback parameters space. The occurrence of RPP is furthermore associated with a topological change in the bifurcation diagram and accompanied by the creation of a new type of bifurcation bridge between a mode and an antimode.

“…In this paper, we theoretically investigate the phenomenon of low frequency fluctuations (LFF) [1,2] in a semiconductor laser subject to delayed optical self-feedback. In the LFF regime, the laser electric field amplitude is bound by a low-frequency envelope that possesses amplitude dropouts at irregular times, i.e.…”

We investigate the dynamic mechanisms for low frequency fluctuations in semiconductor lasers subject to delayed optical feedback, using the Lang-Kobayashi model. This system of delay differential equations displays pronounced envelope dynamics, ranging from erratic, so called low frequency fluctuations to regular pulse packages, if the time scales of fast oscillations and envelope dynamics are well separated. We investigate the parameter regions where low frequency fluctuations occur and compute their Lyapunov spectrum. Using geometric singular perturbation theory, we study this intermittent chaotic behavior and characterize these solutions as bursting slow-fast oscillations.
