Abstract
In some aspects, an optic is disclosed that includes a light input interface having a rippled surface that can mix the light incident thereon as the light propagates within the optic from the rippled surface to a peripheral surface of the optic, which is configured to redirect the light incident thereon to an output surface through which the light exits the optic.
