Integrated optics platforms offer the possibility to implement compact photonic devices for nonlinear optics applications. Modern nanofabrication facilities allow the fabrication of sub-micron-sized waveguide geometries that confine light to reach very high optical intensities. These intensities enable efficient nonlinear processes that are further enhanced by using materials with high nonlinea...

We show that the nonlinear phase shift produced by a ring resonator constructed from a given nonlinear optical material can be greater than the phase shift produced by a single pass through an infinite length of the same material when linear and nonlinear absorption are taken into consideration. The figure of merit (defined by the phase shift times the throughput) also improves for the ring res...

In order to better understand the mechanical properties of biological cells, characterization and investigation of their material behavior is necessary. In this paper hyperelastic Neo-Hookean material is used to characterize the mechanical properties of mouse oocyte cell. It has been assumed that the cell behaves as continuous, isotropic, nonlinear and homogenous material for modeling. Then, by...

Silos are structures that are used for storing different types of granular material. Dynamic behavior of silos under seismic loads is very complex. In this paper seismic behavior of steel silos with different height to diameter ratios is investigated by considering granular material-structure interaction using ABAQUS finite element package. Silo wall is modeled by shell elements and its behavio...

The field of nonlinear optics has developed rapidly since its beginning in 1961. This development is in both the theory of nonlinear effects and the theory of nonlinear interactions in solids, and in the applications of nonlinear devices. This review discusses nonlinear interactions in solids and the resultant nonlinear coupling of electromagnetic waves that leads to second harmonic generation,...

Within the context of the Maxwell Garnett model, we calculate the nonlinear susceptibility of a composite optical material comprised of spherical inclusion particles contained within a host material. We allow both constituents to respond nonlinearly and to exhibit linear absorption. Our treatment takes complete account of the tensor nature of the nonlinear interaction, under the assumption that...

We exploit theoretically a new class of magneto-controlled nonlinear optical material based on ferrofluids in which ferromagnetic nanoparticles are coated with a nonmagnetic metallic nonlinear shell. Such an optical material can have anisotropic nonlinear optical properties and a giant enhancement of nonlinearity, as well as an attractive figure of

We detected the second-order nonlinear response from single isolated spheres comprised from a centrosymmetric material but covered by a layer of a material with strong second-order nonlinear properties and isolated from an ensemble by the optical trapping technique. We show that when large size parameter spheres are used, the measured second-harmonic efficiency deviates strongly from the predic...

We report the first experimental demonstration of two-dimensional spatial solitary waves in secondorder nonlinear optical material. When an intense optical beam is focused into a phase-matchable second-order nonlinear material, the fundamental and generated second-harmonic fields are mutually trapped as a result of the strong nonlinear coupling which counteracts both diffraction and beam walkoff.

numerical modeling of machining processes is of significance in the parametric analysis and optimization of their performance. in this paper, a finite element-based model of abrasive waterjet (awj) cutting of a ductile material is presented with the help of an explicit, nonlinear finite element method. in this model, both solid-solid interaction and fluid-structure interaction are considered. t...
