Light propagation through nanophotonics wormholes

TL;DR

This paper explores how light behaves in a 3D nanophotonic structure shaped like a traversable wormhole, revealing significant phase and group velocity changes, and proposes a feasible experimental realization.

Contribution

It introduces a novel nanophotonic structure mimicking a spacetime wormhole and analyzes light propagation effects within it, bridging general relativity concepts with nanophotonics.

Findings

Light experiences significant phase shifts in the wormhole structure

Group velocities of light are altered by the curved geometry

Experimental realization with current nanophotonics technology is feasible

Abstract

We consider the propagation of light along a 3D nanophotonic structure with the spatial shape of a spacetime containing a traversable wormhole. We show that waves experience significant changes of phase and group velocities when propagating along this curved space. This experiment can be realized with state-of-the-art nanophotonics technology.
