Abstract
A fast spectral modulator for modulating intensity, phase, and spectrum of light beam, is described in the present invention. The spectral modulator comprises at least one liquid crystal composite and a photonic structure. Said at least one liquid crystal composite is made of a liquid crystal and porous microparticles infiltrated within said liquid crystal, wherein: (i) said porous microparticles have an average refractive index approximately equals to one of the liquid crystal principal refractive indices; and (ii) concentration of said microparticles in said composite is less than 0.1% for avoiding significant light scattering.
