An optic device includes a multilayer zone forming a redirection section for redirecting and transmitting photons through total internal reflection, each multilayer zone including a high index material having a first real refractive index n1 and a first absorption coefficient &bgr;1, a low index material having a second real refractive index n2 and a second absorption coefficient &bgr;2, and a grading zone disposed between the high index material and the low index material and including a grading layer having a third real refractive index n3 and a third absorption coefficient &bgr;3, wherein n1>n3>n2. |
