Abstract
Light-emitting devices and/or systems are described. In some embodiments, light-emitting devices and/or systems can recycle at least some light generated by a light-generating region of the light-emitting device. In one embodiment, a light- emitting system comprises a light-emitting device including a light-generating region, a polarization manipulation region that alters a polarization state of at least some light from a first polarization state to a second polarization state, wherein the polarization manipulation region comprises a plurality of features, and a feedback element that returns, to the polarization manipulation region, at least some light having the first polarization state and outputs at least some light having the second polarization state, wherein the polarization manipulation region is disposed at least partially between the light-generating region and the feedback element.
