Abstract
An omnidirectional reflector that reflects a band of electromagnetic radiation of less than 100 nanometers when viewed from angles between 0 and 45 degrees is provided. The omnidirectional reflector includes a multilayer stack having a plurality of layers of high index of refraction material and a plurality of layers of low index of refraction material. In addition, the plurality of high index of refraction material layers and low index of refraction material layers are alternately stacked on top of or across each other and provide a non-periodic layered structure.
