Scientists have designed a way to levitate and propel objects using only light, by creating nanoscale patterns on the objects’ surfaces.

Though still theoretical, the work is a step toward developing a spacecraft that could reach the nearest planet outside of our solar system in 20 years, powered and accelerated only by light.

Decades ago, the development of so-called optical tweezers enabled scientists to move and manipulate tiny objects, like nanoparticles, using the radiative pressure from a sharply focused beam of laser light.

This work formed the basis for the 2018 Nobel Prize in Physics. However, optical tweezers are only able to manipulate very small objects and only at very short distances.

“One can levitate a ping pong ball using a steady stream of air from a hairdryer. But it wouldn’t work if the ping pong ball were too big, or if it were too far away from the hair dryer, and so on,” said Ognjen Ilic, a postdoctoral scholar at California Institute of Technology (Caltech) in the US.

With the new research, published in the journal Nature Photonics, objects of many different shapes and sizes — from micrometers to meters — could be manipulated with a light beam. The key is to create specific nanoscale patterns on an object’s surface.

This patterning interacts with light in such a way that the object can right itself when perturbed, creating a restoring torque to keep it in the light beam.

Thus, rather than requiring highly focused laser beams, the objects’ patterning is designed to “encode” their own stability. The light source can also be millions of miles away.

“We have come up with a method that could levitate macroscopic objects,” said Harry Atwater, from Caltech.

“There is an audaciously interesting application to use this technique as a means for propulsion of a new generation of spacecraft. We’re a long way from actually doing that, but we are in the process of testing out the principles,” he said.

In theory, this spacecraft could be patterned with nanoscale structures and accelerated by Earth-based laser light. Without needing to carry fuel, the spacecraft could reach very high, even relativistic speeds and possibly travel to other stars.

Atwater also envisions that the technology could be used here on Earth to enable rapid manufacturing of ever-smaller objects, like circuit boards.
