1. A photonic reflector device, comprising:
a first layer comprising a first material contacting a second material, the first and second materials having a non-planar interface therebetween, wherein a first refractive index of the first material is at least 1.1 times a second refractive index of the second material;
a second layer comprising a third material and a fourth material having different refractive indices from one another, wherein the third and fourth materials are configured such that the second layer has a periodic optical potential along at least one dimension; and
a third layer comprising a plurality of inclusions in a first matrix material, wherein a third refractive index of the first matrix material is larger than a fourth refractive index of a fifth material of the inclusions.
