Quantum Pump Depletion and Multicomponent Schrödinger-Cat-Like States in Doubly Pumped Intraresonance Kerr Microresonators
Ranjit Singh, Alexander E. Teretenkov
We investigate quantum pump depletion and non-Gaussian state generation in doubly pumped Kerr microresonators operating in the intraresonance regime. The pump modes are treated qua…

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…

Sub-Poissonian Light in a Waveguide Kerr-medium
R. Singh, A. E. Teretenkov, A. V. Masalov
Waveguides on a chip represent a new medium for implementing nonlinear optical transformations of light. Modern chip waveguides are attractive due to their…
