Gravitational lens on a chip

Nature Photonics, 2013
Massive objects in space act as gravitational lenses, bending and focusing light. Scientists have now created a photonic analogue of a gravitational lens on a chip, and have shown that it is strong enough to force light into orbits.

Two-component gravitational lens

Russian Physics Journal, 2013
UDC 524 The propagation of light rays in a spherically symmetric galactic gravitational field generated by dark matter as well as by the baryonic component is investigated. Primary attention is given to the case where the contributions of both these components to gravitational lensing are comparable.

The black hole as a gravitational ‘‘lens’’

American Journal of Physics, 1987
We discuss the ‘‘images’’ formed when the light from a distant source suffers a large deflection in the intense gravitational field in the immediate vicinity of a Schwarzschild black hole. The light can circle around the black hole one or several times, and therefore give rise to a sequence of images.
