Parity-Time Anti-Symmetric Parametric Amplifier
Diana A. Antonosyan, Alexander S. Solntsev, Andrey A. Sukhorukov
We describe the process of parametric amplification in a directional coupler of quadratically nonlinear and lossy waveguides, which belong to a class of optical systems with spatia…
Effect of loss on photon-pair generation in nonlinear waveguides arrays
Diana A. Antonosyan, Alexander S. Solntsev, Andrey A. Sukhorukov
We describe theoretically the process of spontaneous parametric down-conversion in quadratic nonlinear waveguide arrays in the presence of linear loss. We derive a set of discrete…
Chirped quasi-phase-matching with Gauss sums for production of biphotons
D. A. Antonosyan, A. R. Tamazyan, G. Yu. Kryuchkyan
We study the theory of linearly chirped biphoton wave-packets produced in two basic quasi-phase-matching configurations: chirped photonic-like crystals and aperiodically poled crys…
Phase-reversed structures in superlattice of nonlinear materials
D. A. Antonosyan, G. Yu. Kryuchkyan
We present detailed description of so-called phase-reversed structures that are characterized by two grating wave vectors allowing simultaneously phase-match two parametric three-w…
Three-photon states in nonlinear crystal superlattices
Diana A. Antonosyan, Tigran V. Gevorgyan, Gagik Yu. Kryuchkyan
It has been a longstanding goal in quantum optics to realize controllable sources generating joint multiphoton states, particularly, photon triplet with arbitrary spectral characte…
Exactly solvable Ising--Heisenberg chain with triangular XXZ-Heisenberg plaquettes
Diana Antonosyan, Stefano Bellucci, Vadim Ohanyan
A mixed Ising-Heisenberg spin system consisting of triangular XXZ-Heisenberg spin clusters assembled into a chain by alternating with Ising spins interacting to all three spins in…
