Abstract

A modulator material layer includes a polymer matrix formed of a plurality of cross-linked polymer molecules and a plurality of droplets of liquid crystals within the polymer matrix. A planar macrocycle dye is dispersed within the plurality of droplets of liquid crystals. The planar macrocycle dye can include one or more of a phthalocanine, a porphyrin, a naphthalocyanine, a metallophthalocyanine, a metalloporphyrin, or a metallonaphthalocyanine.
