Isochrons and Phase Response Curves are crucial for understanding synchronization.

Stable phase-locking conditions are identified using these structures.

Frequency combs with discrete spectra can be achieved through periodic modulation.

Abstract

The global structure of the Isochrons and the corresponding Phase Response Curves are, for the first time, investigated and numerically computed for the fundamental photonic oscillator consisted of an Optically Injected Laser. Their crucial role in the synchronization dynamics under a periodic modulation of the injection beam is shown, along with their capability for providing conditions for stable phase-locking and periodic outputs with discrete equidistant spectra in the form of frequency combs.
