Lighthole
Lighthole is a term that appears in speculative or fictional contexts to refer to an optical construct that provides a direct, highly efficient pathway for light to traverse an obstacle or medium. It is not a standard concept in mainstream optics or physics.
In theoretical discussions, a lighthole might be imagined as an engineered aperture, nano-scale channel, or surface
Terminology note: the phrase "light hole" does exist in semiconductor physics as the name of the light-hole
In literature and media, lighthole can be used as a metaphor for a portal or conduit that
