Simulation of giant tidal force of wormhole using curved optical spaces

The tidal force of gravity is usually a weak force and is considered only in the movement of celestial bodies. However, in the presence of a very strong gravitational field, such as that of black holes and wormholes, tidal force also has an effect on light wave packets. In this work, we employ a curved optical waveguide to mimic the giant tidal force of wormholes on optical beams. We calculate the beam spreading caused by tidal force using general relativity. The theoretical calculations were in agreement with the experimental results. Our results show that the giant tidal force induces the divergence of optical deflection at the throat of a wormhole. This experimental system promises to be an effective methodology for the future studies mimicking gravitation.
