When we think about highly sensitive medical testing, we often imagine a hospital laboratory filled with large instruments, trained technicians, and carefully controlled conditions. This is especially true for optical biosensing, ...
The task of gently transporting a microscopic particle from one point to another along a winding path, and then bringing it back using nothing more than a single, compact chip is a challenge we set out to address in our new ...
A new type of hologram technology has been developed that uses the motion of light as a key, revealing information only under specific conditions. This is gaining attention as a novel approach that can simultaneously overcome ...
Reaching the nearest star system, Alpha Centauri, would take hundreds of thousands of years using current rocket propulsion technology. Researchers in the J. Mike Walker '66 Department of Mechanical Engineering at Texas A&M ...
Have you ever wished to drive microscopic matter along an arbitrarily tailored trajectory instead of just a circle? That's exactly what we set out to achieve.
A collaborative research group has developed a fully automated roll-to-roll manufacturing platform capable of producing large-area visible metalenses at a rate of 300 units per second, marking a major breakthrough in translating ...
Researchers at The University of Osaka, in collaboration with ULVAC, Inc. and Ritsumeikan University, have developed a new LED structure that generates circularly polarized light from a single chip. By combining a semipolar ...
Researchers from the Monash University School of Physics and Astronomy have flipped a long-held assumption in optics, showing that deliberately introducing controlled disorder into ultra-thin optical devices can dramatically ...
Optical vortices—light beams carrying orbital angular momentum (OAM)—are characterized by helical wavefronts and phase singularities. While they have been widely studied in recent decades, two fundamental limitations have ...
Light can carry angular momentum in two distinct ways. One comes from polarization, which describes how the electric field rotates. The other comes from the shape of the wavefront itself, which can twist like a corkscrew ...
