We present an overview of nonlinear phenomena related to optical quadratic solitons—
intrinsically multi-component localized states of light, which can exist in media without …

Recently, there has been an explosion of interest in mirrorless distributed feedback (DFB)
lasing in chiral liquid crystals (CLCs)[1]. The reason for this interest is related to the …

This book merges theoretical and experimental works initiated in 1997 from consideration of
periodical artificial dielectric structures comprising magneto-optical materials. Modern …

An overview of the most relevant properties of photonic crystals is presented considering 1D,
2D and 3D structures. The emphasis is on nonlinear properties both of the second and third …

We demonstrate significant enhancement of second-order nonlinear interactions in a one-
dimensional semiconductor Bragg mirror operating as a photonic band gap structure. The …

The damage in fused silica and CaF 2 crystals induced by wavelength tunable femtosecond
lasers is studied. The threshold fluence is observed to increase rapidly with laser …

We have carried out a spectroscopic study on a prototype ferroelectric nematic material
(RM734) doped with a non-polar chiral compound. The mixture presents two chiral nematic …

The transfer matrix method has been widely used to calculate the scattering of
electromagnetic waves. In this paper, we develop the conventional transfer matrix method to …

By exploiting the unique properties of periodic stratified media we demonstrate
simultaneously phase matching and enhancement of the optical field under second order …

Using the concept of an effective medium, we derive coupled mode equations for nonlinear
quadratic interactions in photonic band gap structures of finite length. The resulting …
