Journal ArticleDOI
Multiplexed holographic transmission gratings recorded in holographic polymer-dispersed liquid crystals: static and dynamic studies
Sébastien Massenot,Jean-Luc Kaiser,Maria Camacho Perez,Raymond Chevallier,Jean-Louis de Bougrenet de la Tocnaye +4 more
TL;DR: The optimization of the experimental parameters of two multiplexed holographic transmission gratings recorded in holographic polymer-dispersed liquid crystals is investigated and the response of the holograms to an electric field is studied.
Journal ArticleDOI
Study of the dynamic formation of transmission gratings recorded in photopolymers and holographic polymer-dispersed liquid crystals
TL;DR: The rigorous coupled-wave theory method provides information on higher harmonics of the refractive profile (not only on the first harmonic as when the classical Kogelnik theory is applied) and Measurements concerning the second harmonic validate the modeling.
Journal ArticleDOI
Chirped switchable reflection grating in holographic polymer-dispersed liquid crystal for spectral flattening in free-space optical communication systems
Jean-Luc Kaiser,Raymond Chevallier,Jean-Louis de Bougrenet de la Tocnaye,Hayqing Xianyu,Gregory Philip Crawford +4 more
TL;DR: This CSRG is a spatial wavelength-selective flattener in a free-space dynamic gain equalizer for use in wavelength-division multiplexing (WDM) networks and permits the management of the spectral power of a WDM stream with an attenuation range of 6 dB.
Journal ArticleDOI
Light propagation in the pseudo-paraxial Fresnel approximation
TL;DR: Simulation results in the field of fiber optics are presented showing the gain in accuracy with respect to the usual Fresnel approximation and the reduction of computing time withrespect to other non-paraxial propagation methods.
