“…In the experiment, they clearly demonstrated large nonlinear phase shifts. This experiment paved the way to the experimental investigation in other nonlinear quadratic materials: ␤-barium borate by means of self-diffraction, 12 potassium niobate, 13 potassium dihydrogen phosphate, 14 organic N-(4-nitrophenyl-Lprolinol, 15 and periodically poled lithium niobate. 16 A theoretical description of nonlinear phase distortions in (2) materials was made by numerical integration of the nonlinear differential equations that describe the propa-gation of plane waves.…”

A theoretical analysis of the nonlinear quadratic interaction between two monochromatic plane waves at frequencies and 2 in a Fabry-Perot cavity shows that all-optical control of reflectivity and transmissivity of the fundamental beam is possible under suitable conditions. We report all-optical switching of the fundamental beam for cavity lengths that vary from a few micrometers to a few millimeters. Specifically, we show that 100% all-optical switching can occur for a 6-m cavity when the nonlinear coefficient is not greater than 20 pm/V and the input intensity does not exceed 10 GW/cm 2. Our analytical results are obtained without use of the slowly varying envelope approximation and without resort to the undepleted-pump approximation.

“…Furthermore, it provides electromagnetic fields with an exceptionally wide range of nonclassical effects. Most importantly this device has been implemented [8][9][10][11][12][13][14] and applied in many experimental approaches, e.g. in picosecond switching induced by saturable absorption [15], optical multi-mode interference devices based on self-imaging [16], and photonic bandgap structures in planar nonlinear waveguides [17].…”

Quantum Statistical Properties of the Codirectional Kerr Nonlinear Coupler in Terms of su 2 $\left (2\right ) $ Lie Group in Interaction with a Two-level Atom

The problem of the codirectional Kerr coupler has been considered several times from different point of view. In the present paper we introduce the interaction between a two-level atom and the codirectional Kerr nonlinear coupler in terms of su(2) Lie algebra. Under certain conditions we have adjusted the Kerr coupler and consequently we have managed to handle the problem. The wave function is obtained by using the evolution operator where the Heisnberg equation of motion is invoked to get the constants of the motion. We note that the Kerr parameter χ as well as the quantum number j plays the role of controlling the atomic inversion behavior. Also the maximum entanglement occurs after a short period of time when χ = 0. On the other hand for the entropy and the variance squeezing we observe that there is exchange between the quadrature variances. Furthermore, the variation in the quantum number j as well as in the parameter χ leads to increase or decrease in the number of fluctuations. Finally we examined the second order correlation function where classical and nonclassical phenomena are observed.

“…This implies that a focusing or defocusing behaviour depends on the material arrangement with respect to the incident field to be doubled, for instance orientation, temperature, periodic poling, applied voltage, etc. Some of these important characteristics were verified in bulk by DeSalvo et al in a 1mm KTP crystal at 1.064µm via Z-scan, 18 and later on by Danielius et al in BBO via self-diffraction, 24 by Ou in potassium niobate inside a cavity, 25 by Fazio et al in KDP, 26 by Wang et al 2 7 in the organic NPP and by Vidakovic et al in periodically poled lithium niobate (PPLN). 28 The shown similarity between a phase mismatched SHG process and a cubic frequency degenerate interaction is, however, of limited use.…”
