Quantum states with nonlinear squeezing are a necessary resource for deterministic implementation of high-order quadrature phase gates that are, in turn, sufficient advanced quantum information processing. We demonstrate this class can be deterministically prepared by employing single Kerr gate accompanied suitable Gaussian The required coupling depends on the energy initial system and made arb...

Achievable information rates of optical communication systems are inherently limited by nonlinear distortions due to the Kerr effect occurred in fibres. These impairments become more significant for with larger transmission bandwidths, closer channel spacing and higher-order modulation formats. In this paper, efficacy nonlinearity compensation techniques, including both digital back-propagation...

We study modulational instability (MI) of plane waves in nonlocal nonlinear Kerr media. For a focusing nonlinearity we show that, although the nonlocality tends to suppress MI, it can never remove it completely, irrespective of the particular profile of the nonlocal response function. For a defocusing nonlinearity the stability properties depend sensitively on the response function profile: for...

Nanoscale modal confinement is known to radically enhance the effect of intrinsic Kerr and Raman nonlinearities within nanophotonic silicon waveguides. By contrast, stimulated Brillouin-scattering nonlinearities, which involve coherent coupling between guided photon and phonon modes, are stifled in conventional nanophotonics, preventing the realization of a host of Brillouin-based signal-proces...

Nonlinear optical materials comprise the foundation of modern photonics, offering functionalities ranging from ultrafast lasers to optical switching, harmonic and soliton generation. Optical nonlinearities are typically strong near the electronic resonances of a material and thus provide limited tuneability for practical use. Here we show that in plasmonic nanorod metamaterials, the Kerr-type n...
