A multilayer photonic structure may include a plurality of coating layers of high index dielectric material of index of refraction nand a plurality of coating layers of low index dielectric material of index of refraction nalternately arranged with a first coating layer and a last coating layer of the multi-layer photonic structure comprise low index material. An index-thickness of each coating layer of the multilayer photonic structure is different than every other coating layer of the multilayer photonic structure. The multilayer photonic structure has a first high reflectivity bandwidth, a second high reflectivity bandwidth and a low reflectivity bandwidth wherein the low reflectivity bandwidth is positioned between the first high reflectivity bandwidth and the second high reflectivity bandwidth.
