Abstract
Exemplary devices may include a substrate, a dielectric layer formed on the substrate, a first light source configured to emit first light characterized by a first wavelength, a second light source configured to emit second light characterized by a second wavelength different from the first wavelength, and a third light source configured to emit third light characterized by a third wavelength different from the first wavelength and the second wavelength. The first light source may be natively formed on a first region of the substrate and arranged within a first opening of the dielectric layer. The second light source may be natively formed on a second region of the substrate and arranged within a second opening of the dielectric layer. The third light source may be natively formed on a third region of the substrate and arranged within a third opening of the dielectric layer.
