Abstract
An optoelectronic device includes a carrier substrate, with a lower distributed Bragg-reflector (DBR) stack disposed on an area of the substrate and including alternating first dielectric and semiconductor layers. A set of epitaxial layers is disposed over the lower DBR, wherein the set of epitaxial layers includes one or more III-V semiconductor materials and defines a quantum well structure and a confinement layer. An upper DBR stack is disposed over the set of epitaxial layers and includes alternating second dielectric and semiconductor layers. Electrodes are coupled to apply an excitation current to the quantum well structure.
