We show experimentally and numerically that cholesteric-type metal-dielectric structures, made of twisted sub-wavelength hole elliptical–shaped arrays, exhibit strong optical activity and circular dichroism. The experimental demonstration is carrie

Physical Review E. 79
The ability of two-dimensional (2D) photonic crystals (PC) for high enhancements of nonlinear processes is analyzed in the case of a degenerate band edge when two symmetrical diffracted beams are generated by Bragg diffraction in the 2D-PC. Calculati

International audience; Large refractive index changes have been measured at the band edge frequency of 1D photonic crystals. Results concerning both thin and thick samples of high and low refractive index contrast respectively are presented. The ver

Controlling Light with Light: Photorefractive Effects, Photosensitivity, Fiber Gratings, Photonic Materials and More.
Photonic crystals show several properties that present great interest for the implementation of nonlinear optical functions. We will show how light localization in these structures will largely increase the efficiency of the nonlinear mechanism.

One way to realize such a light localization is to structure the material at the wavelength size level creating thus a photonic crystal that may present a photonic band gap that prevents propagation of light in it for a given frequency bandwidth. Nea

International audience; We present a modeling of a degenerate four-wave-mixing nonlinear process in one-dimensional photonic crystals. The model is based on the nonlinear extension of the transfer-matrix description of propagation in the structure. T
