Abstract
A layered structure includes a first layer being a single material and a cavity coupled to the first layer. The first layer includes a porous region to form a first distributed Bragg reflector (DBR). The porous region includes alternating first porous and second porous sublayers of the single material to form the first DBR. The cavity includes an active region to generate radiation, detect radiation, or both. Advantageously, the layered structure and method of forming the layered structure improves the speed of manufacturing DBRs, reduces strain in the layered structure, reduces the size of the layered structure, and increases throughput.
