Bright-soliton frequency combs and dressed states in chi(2) microresonators
D. N. Puzyrev, V. V. Pankratov, A. Villois +1
We present a theory of the frequency comb generation in the high-Q ring microresonators with quadratic nonlinearity and normal dispersion and demonstrate that the naturally large d…
Photon-photon polaritons in chi(2) microresonators
D. V. Skryabin, V. V. Pankratov, A. Villois +1
We consider a high-Q microresonator with nonlinearity under conditions when the coupling rates between the sidebands around the pump and second harmonic exceed the dampin…
Threshold of complexity and Arnold tongues in Kerr ring microresonators
D. V. Skryabin, Z. Fan, A. Villois +1
We show that the threshold condition for two pump photons to convert into a pair of the sideband ones in Kerr microresonators with high-quality factors breaks the pump laser parame…
Irreversible dynamics of vortex reconnections in quantum fluids
Alberto Villois, Davide Proment, Giorgio Krstulovic
We statistically study vortex reconnections in quantum fluids by evolving different realizations of vortex Hopf links using the Gross--Pitaevskii model. Despite the time-reversibil…
Frequency comb generation via cascaded second-order nonlinearities in microresonators
Jan Szabados, Danila N. Puzyrev, Yannick Minet +5
Optical frequency combs are revolutionising modern time and frequency metrology. In the past years, their range of applications has increased substantially, driven by their miniatu…
Frequency combs in a microring optical parametric oscillator
Alberto Villois, Nikita M. Kondratiev, Ingo Breunig +2
We report the soliton frequency comb generation in microring optical parametric oscillators operating in the down-conversion regime and with the simultaneous presence of the $χ^{(2…
