Abstract: In one embodiment, an electronic device is provided and methods for making the same, as well as devices and sub-assemblies including the same. For example, such an electronic device (FIG. 4) may include a first electronic component (172) designed to be photoactive to a first radiation having a first wavelength, a second electronic component (174) designed to be photoactive to a second radiation having a second wavelength, a first mirror stack (30) adjacent to the first and second electronic components, where the first mirror stack includes a first pair of layers designed to reflect the first radiation and a second mirror stack (40) adjacent to the first and second electronic components, where the second mirror stack includes a second pair of layers designed to reflect the second radiation.
