We discuss a model comprising two coupled nonlinear oscillators (Kerr-like nonlinear
coupler) with one of them pumped by an external coherent excitation. Applying the method …

The intermodal entanglement in a two-channel symmetric nonlinear coupler, operated with
Kerr nonlinearity was investigated using the analytical method based on the Heisenberg …

Quantum behavior of two oscillator modes, with mutually balanced gain and loss and
coupled via linear coupling (including energy conserving as well as energy non-conserving …

In the present communication, we consider the quantum properties for the codirectional
three-mode Kerr nonlinear coupler. We investigate single-, two-and three-mode quadrature …

In this paper, we investigate the single-mode quantum properties of the codirectional Kerr
nonlinear coupler when the frequency mismatch is involved and a condition for an exact …

We study the evolution of the nth-order single-mode squeezing, sum-and difference-
squeezing for a codirectional Kerr nonlinear coupler. We show that squeezing factors can …

The properties of squeezing, in relation to the different interaction frequencies of the input
modes in three-mode Kerr nonlinear coupler consisting of two linearly-coupled Kerr …

The generation of squeezed states of light in a two-mode Kerr nonlinear directional coupler
(NLDC) was investigated using two different methods in quantum mechanics. First, the …

High resolution effects are obtained in simple diffraction patterns from very narrow apertures
producing evanescent waves. The quantization of such waves is described by the equations …

The problem of quantum state exchange between three coupled quantum harmonic
oscillators (which can represent interacting modes of the electromagnetic field in nonlinear …
