An electronic device includes a radiation-emitting component, a radiation-responsive component, or a combination thereof. In one embodiment, the electronic device includes a substrate and a first structure overlying the substrate. The electronic device also includes a second structure that includes a first layer, wherein the first layer has a first refractive index, and the first layer includes a first edge. The electronic device further includes a second layer overlying at least portions of the first structure and the second structure at the first edge. The second layer has a second refractive index that is lower than the first refractive index. In another embodiment, the first structure includes a layer having a perimeter and a pattern lying within the perimeter. The pattern extends at least partly though the first layer to define an opening with a first edge. In another embodiment, a process is used to form the electronic device.
