1. An article comprising:
an optical transforming layer having a first surface and a second surface opposite the first surface, the first surface and the second surface bound by a perimeter of the optical transforming layer; and
a guide region positioned inside and adjacent to at least a portion of the perimeter of the optical transforming layer, wherein the guide region extends at least partially between the first surface to the second surface, wherein the guide region comprises an inlet end positioned adjacent to the first surface and an outlet end positioned adjacent the second surface, wherein the guide region propagates light from the inlet end to the outlet end such that the light is directed from the first surface to the second surface, the guide region comprising:
a phase-separated glass comprising a quasi-random structure of a continuous network phase and a discontinuous phase, wherein a relative difference in index of refraction between the continuous network phase and the discontinuous phase is greater than or equal to 0.3%, wherein the discontinuous phase comprises elongated shaped regions aligned along a common axis and having an aspect ratio greater than or equal to 10:1.
