Towards Schrödinger Cat States in the Second Harmonic Generation
Ranjit Singh, Leonid A. Barinov, Grigori G. Amosov +1
We investigate the quantum evolution of the pump field in second-harmonic generation under strong pump depletion. Starting from a coherent state, the pump develops a nonclassical p…

Intraresonance frequency combs in Kerr microresonators
Andrei N. Danilin, Timur R. Yunusov, Ekaterina S. Vahnitskaya +7
For more than 20 years, optical microresonators have served as the backbone of integrated nonlinear photonics, exploiting Kerr nonlinearity to generate octave-spanning frequency co…
