Résumé :

We theoretically investigate the dynamics, bifurcation structure, and stability of quadratic dark localized dissipative states arising in cavity-enhanced second-harmonic generation. These states, formed through the locking of plane front waves, undergo collapsed homoclinic snaking and may exhibit oscillatory dynamics.
