We present a review of theoretical and experimental aspects of multiphoton quantum optics.
Multiphoton processes occur and are important for many aspects of matter–radiation …

Possible squeezed states generated in a three-waveguide nonlinear coupler operating with
second harmonic generation is discussed. This study is carried out using two well-known …

Higher-order nonclassical properties of fields propagating through a codirectional
asymmetric nonlinear optical coupler which is prepared by combining a linear waveguide …

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 …

We discuss a model comprised of a chain of three Kerr-like nonlinear oscillators pumped by
two modes of external coherent field. We show that the system can be treated as nonlinear …

Optical couplers employing evanescent waves play an important role in optics,
optoelectronics and photonics because they may be conveniently used in the switching of …

Schemes for optical-state truncation of two cavity modes are analysed. The systems, referred
to as the nonlinear quantum scissors devices, comprise two coupled nonlinear oscillators …

We investigate the nonclassical properties of output fields propagated through a
contradirectional asymmetric nonlinear optical coupler consisting of a linear waveguide and …

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

In this paper thermally induced entanglement between a two-level atom and photons inside
a bimodal nonlinear coupler is studied. The interaction occurs in the presence of a …
