Dark quadratic localized states and collapsed snaking in doubly resonant dispersive cavity-enhanced second-harmonic generation

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.

Theoretical investigation into quadratic dark localized dissipative states in cavity-enhanced second-harmonic generation reveals their dynamics, bifurcation structure, and stability. These states, formed through the locking of plane front waves, exhibit collapsed homoclinic snaking and potentially oscillatory dynamics.
