Bifurcation structure of a swept-source laser

Abstract

We numerically analyze a delay differential equation model of a short-cavity semiconductor laser with an intracavity frequency swept filter and reveal a complex bifurcation structure responsible for the asymmetry of the output characteristics of this laser. We show that depending on the direction of the frequency sweep of a narrowband filter, there exist two bursting cycles determined by different parts of a continuous-wave solutions branch.

“…The exit from the blockade regime is also sensitive to the chosen value of H + /H − and the scan parameters. Generally, nonlinear dynamics under conditions when a parameter is swept across the bifurcation points is an area of research attracting attention in optics and beyond (see, e.g., [24,25] and references therein). The reverse, i.e., ε-positive to ε-negative, scan shows the much narrower range of the soliton-blockade in the plus field, and no solitons in the minus field (see the right column in Figure 6).…”
