“…The synchronization dynamics of the self-sustained nonlinear oscillations with the external driving depends crucially on the phase response of the system and may result either to phase locking or chaotic outputs. In this work we review the importance of the Isochrons for the study of complex synchronization dynamics of Optically Injected Semiconductor Lasers under external periodic modulation of the injected beam 4 and discuss potential applications related to remote clock synchronization for communications applications requiring coherent receivers as well as geolocation applications based on precise phase-shift measurements.…”

The concept of the Isochrons is introduced for the study of the phase response of an optically injected semiconductor laser. The global structure of the Isochrons and the corresponding phase response curves are numerically computed and systematically dissected in terms of their characteristics. Their paramount role in the synchronization properties under an external periodic modulation of the injection beam is shown along with their ability for providing conditions for stable phase locking and highly customizable periodic outputs with discrete equidistant spectra in the form of frequency combs. Potential applications related to remote clock synchronization for communications requiring coherent receivers as well as geolocation applications based on precise phase-shift measurements, are discussed.

The response of a tunable photonic oscillator, consisting of an optically injected semiconductor laser, under an injected frequency comb is considered with the utilization of the concept of the time crystal that has been widely used for the study of driven nonlinear oscillators in the context of mathematical biology. The dynamics of the original system reduce to a radically simple one-dimensional circle map with properties and bifurcations determined by the specific features of the time crystal fully describing the phase response of the limit cycle oscillation. The circle map is shown to accurately model the dynamics of the original nonlinear system of ordinary differential equations and capable for providing conditions for resonant synchronization resulting in output frequency combs with tunable shape characteristics. Such theoretical developments can have potential for significant photonic signal-processing applications.

It has been experimentally and theoretically analyzed that noise-induced excitability in quantum well and quantum dot semiconductor laser systems usually produces sharp spike patterns of non-uniform amplitude. In this paper, we experimentally record that a quantum cascade oscillator injected externally with a monochromatic laser beam exhibits a series of highly uniform spike trains, which occur in the proximity of the saddle-node bifurcation. Theoretical analysis based on a properly designed single-mode rate equation model endowed with quantum noise reveals that this high uniformity has its primary origin in the ultrashort carrier lifetime of the quantum cascade laser gain medium that is typically close to 1 ps.
