Saddle-node bifurcation cascade in optically injected lasers

TL;DR

This paper investigates the complex self-similar structures in optically injected lasers, revealing their connection to saddle-node bifurcation cascades and unifying seemingly unrelated phenomena within this framework.

Contribution

It introduces the saddle-node bifurcation cascade as a comprehensive explanation for self-similar structures in optically injected lasers, linking various phenomena.

Findings

Self-similar structures are linked to saddle-node bifurcations.

The phenomena in these lasers are unified under the saddle-node bifurcation cascade framework.

Related phenomena previously considered disconnected are shown to be connected.

Abstract

Self-similar structures converging to accumulation points are observed in optically injected lasers. These structures are associated to saddle-node bifurcations. We found that these phenomena can be properly explained in the framework of saddle-node bifurcation cascade. Apparently not connected phenomena in these lasers are shown to be related within this framework.
