Abstract:
A method of creating a stacked light emitting device that emits desired spectra of light, comprising the steps of:selecting a first light emitting device that emits a first emission spectrum;selecting a second light emitting device that emits a second emission spectrum;for an optical cavity having an optical path length, the optical cavity being delimited by a first reflective layer having a first reflectance and a second reflective layer having a second reflectance, selecting the optical path length, the first reflectance, and the second reflectance such that the optical cavity filters the second emission spectrum of the second light emitting device, disposed between the first reflective layer and the second reflective layer, into a first transmitted spectrum; andfabricating a stacked light emitting device comprising the first light emitting device and the second light emitting device and having the optical cavity, wherein the second light emitting device is disposed between the first reflective layer and the second reflective layer of the optical cavity.
