Report

Effects of spatial quantization and Rabi-shifted resonances in single and double excitation of quantum wells and wires induced by few-photon optical field

Autor: Vasil'ev, Andrey, Tikhonova, Olga

We develop a fully quantum theoretical approach which describes the dynamics of Frenkel excitons and bi-excitons induced by few photon quantum light in a quantum well or wire (atomic chain) of finite size. The eigenenergies and eigenfunctions of the

Peculiarities of Interaction of a Quantum Dot with Non-Classical Light in the Self-Phase Modulation Regime

Autor: Balybin, Stepan N., Zakharov, Roman V., Tikhonova, Olga V.

Influence of the self-phase modulation of quantum light on the induced resonant excitation of a semiconductor quantum dot is studied analytically in the case of the Kerr-nonlinearity of the medium. The phase nonlinearity is found to result actually i

Multimode optical parametric amplification in the phase-sensitive regime

Autor: Frascella, Gaetano, Zakharov, Roman V., Tikhonova, Olga V., Chekhova, Maria V.

Publikováno v: Optics Letters Vol. 46, Issue 10, pp. 2364-2367 (2021)

Phase-sensitive optical parametric amplification of squeezed states helps to overcome detection loss and noise and thus increase the robustness of sub-shot-noise sensing. Because such techniques, e.g., imaging and spectroscopy, operate with multimode

Managing spectral properties and Schmidt mode content of squeezed vacuum light using sum-frequency converter

Autor: Sukharnikov, Vladislav, Sharapova, Polina, Tikhonova, Olga

Capabilities of quantum optical SFG-gate seeded by squeezed light are investigated in the frame of frequency Schmidt modes. Methods to manage and manipulate extensively the properties and mode content of squeezed light are developed. Possibilities to

Experimental reconstruction of spatial Schmidt modes for a wide-field SU(1,1) interferometer

Autor: Frascella, Gaetano, Zakharov, Roman V., Tikhonova, Olga V., Chekhova, Maria V.

We study the spatial mode content at the output of a wide-field SU(1,1) interferometer, i.e. a nonlinear interferometer comprising two coherently-pumped spatially-multimode optical parametric amplifiers placed in sequence with a focusing element in b
