Abstract:
1. A light-guiding structure, comprising: a first solid layer, wherein the first solid layer is transparent; a second solid layer; and a fluid light-tracking layer interposed between the first and second solid layers, wherein the fluid light-tracking layer contains a first fluid and a second fluid, wherein the first fluid and the second fluid are immiscible, wherein at least a portion of the first fluid comprises a coupling region located at a local temperature maximum within the fluid light-tracking layer, wherein a light beam incident on the light-guiding structure and striking the coupling region is deflected by an element of the light-guiding structure at an angle sufficient to confine at least a portion of the deflected light beam within the light-guiding structure as the deflected light beam propagates through the light-guiding structure, wherein the local temperature maximum is the result of localized absorption of a portion of the light beam incident on the light-guiding structure, wherein the coupling region self-aligns with the light beam incident on the light-guiding structure, and wherein a cross-sectional area of the coupling region is less than 10% of a fluid light-tracking layer cross-section.
