Abstract: An assembly having a liquid crystal molecule section, a reflector section, disposed on the liquid crystal molecule section, having a stack of dielectric layers having alternating higher and lower indices of refraction; and an array of electrode sections disposed between a pair of the dielectric layers, one of said pair of dielectric layers having a higher index than the other one of said pair of dielectric layers. The electrodes in the array are interdigitated electrode for producing electric fields parallel to the array. The reflector section is disposed between the liquid crystal molecule section and a thermally conductive substrate.
