Quantum-Optical Mode Gate for Nonclassical Squeezed Light

Vladislav Sukharnikov, Olga V. Tikhonova

A theoretical approach has been developed in the Schmidt mode formalism and photon operators in these modes to describe the spectral properties of the light generated in the nonlinear process of sum-frequency generation. A special regime at which the frequency correlations of photons in the output beams are suppressed has been described in detail. The control of the mode composition and spectral properties of the nonclassical squeezed light used to illuminate the signal channel with the possibility of generating a squeezed vacuum at the sum-frequency mode has been demonstrated at this regime.

Quantum-optical Converter for Squeezed Light

Vladislav Sukharnikov, Olga V. Tikhonova

We propose a scheme based on sum frequency generation seeded by multimode squeezed vacuum light. It provides manipulation of seeding mode weights, tailoring output spectral and temporal signal, generation of squeezed vacuum in sum frequency.

Managing the spatial properties and photon correlations in squeezed non-classical twisted light

Roman V. Zakharov, Olga V. Tikhonova

Abstract Spatial photon correlations and mode content of the squeezed vacuum light generated in a system of two separated nonlinear crystals is investigated. The contribution of both the polar and azimuthal modes with non-zero orbital angular momentum is analyzed. The control and engineering of the spatial properties and degree of entanglement of the non-classical squeezed light by changing the distance between crystals and pump parameters is demonstrated. Methods for amplification of certain spatial modes and managing the output mode content and intensity profile of quantum twisted light are suggested.
