Dissipative polarization domain walls in a passive driven Kerr resonator

Zero-dispersion Kerr solitons in optical microresonators

“…As such, they have been proposed as a superior alternative to bright DS for applications which require the generation of strong comb lines near to the pump center, and have been demonstrated as a source for massively parallel telecommunications 35 . Switching waves have been classed more generally as 'domain walls' connecting two stable homogeneous states in driven dissipative systems, seen in χ (2) optical parametric oscillators 36,37 , semiconductor lasers 38 , birefringent optical fibers 39,40 , and more widely in hydrodynamic systems and more 41 .…”

Vectorial dark dissipative solitons in Kerr resonators

“…1(c) (right panel). Unlike in systems where domain walls are formed leading to the formation of DVDSs [16] obtained for b > 1, here for b = 2/3, the total intensity consists of a vectorial front that is devoid of any topological defects.…”

“…The existence of these structures with different cavity losses for the two polarization components has been predicted in [15]. Such temporally localized structures with orthogonal polarization states have been experimentally realised [16]. More recently, the existence of dark-bright vector solitons arising from a cross-polarization coupling in birefringent fiber lasers have been experimentally shown in [17].…”

“…The dark vectorial dissipative solitons presented in our study should be experimentally observable in all fiber cavities [16] and microresonators [34]. For an optical fiber cavity the experimental settings could be a resonator of length L = 10m, exhibiting a second order dispersion coefficient β 2 53ps 2 /km and nonlinear coefficient γ 0.0043(Wm) −1 , and operating at an input power P in 50mW.…”
