Micron Scale Innovation in Optical Levitation

A research team at Texas A&M University has introduced a novel propulsion concept dubbed metajets, which uses laser beams to lift and steer objects in multiple directions. Led by Dr. Shoufeng Lan, the team’s work, published on April 22, 2026, demonstrates the first optical propulsion system to achieve full three dimensional maneuverability. These micron scale devices are composed of metasurfaces, which are ultrathin materials etched with specific patterns designed to control the behavior of light. By manipulating how light bounces off these surfaces, the researchers can effectively steer the momentum transfer from the laser to the object.

Momentum Transfer Through Nanoscale Engineering

The physical principle behind the metajets is compared to the force exerted by ping pong balls bouncing off a table. As light interacts with the precisely fabricated metasurface, it transfers a small but measurable force that enables controlled motion. Unlike previous optical systems that required shaping the light beam itself to influence an object, the metajet approach builds the control logic into the physical structure of the material. This distinction allows for more flexible force generation and was made possible through high precision fabrication at the Texas A&M AggieFab Nanofabrication Facility.

Scalability Beyond the Microscopic Realm

While the current experimental devices are smaller than the width of a human hair, the researchers maintain that the technology is inherently scalable. Because the force generated by metajets depends primarily on the power of the light source rather than the physical dimensions of the device, the method could theoretically be applied to much larger systems. This scalability is a significant advantage over other proposed light propulsion methods, potentially allowing for the construction of larger spacecraft that retain the agility of microscopic probes.
