Temporal accelerator upgrade idea

If we use fiberoptic tubes in the shape of a warp field we might be able to recreate how gravity in mass works on a weaker but larger scale.

Can we use something that bends energy like how fibre optics bends light to create warp fields out of energy??

We could make a handy expandable network of tubes we create a temporal accelerator for a ship say :-)

Please explore.
