In this paper, we proposed a new mechanism for bistable phase locking that does not require any temporal modulation. The mechanism is inspired in temporal rocking and consists in the injection of a single monochromatic signal that has two opposite phase values. Consider a laser cavity with spherical mirrors tuned to its TEM00 mode. Then a monochromatic signal that is (nearly) resonant with that mode...
The authors present an alternative to rocking that leads to the same type of behaviour, namely the appearance of bistable phase locking and, in the case of large Fresnel number lasers, to stable (phase bistable) cavity solitons and extended patterns. The new type of injection we present here is monochromatic, unlike usual rocking, but it is spatially modulated across the transverse plane of the cavity,...
