We demonstrate a controllable enhancement in the electrostrictive properties of a medium using dilute composite artificial materials. Analytical expressions for the composite electrostriction are derived and used to show that enhancement, tunability

We consider pulse propagation in quadratically nonlinear gratings. Assuming that the phase mismatch between the fundamental and the second-harmonic frequencies deltak is large, we present a perturbation method in deltak(-1). In the well known cascadi

The frequency shift of sources embedded in a two-dimensional photonic cluster composed of circular cylinders is considered and the effects of cluster shape and orientation are investigated. It is found that by carefully tailoring the shape of the clu

We consider defect modes created in complete gaps of 2D photonic crystals by perturbing the dielectric constant in some region. We study their evolution from a band edge with increasing perturbation using an asymptotic method that approximates the Gr
