Scientists use the Lorentz force to stop light in its tracks
- Scientists from AMOLF and Delft University of Technology have discovered a method to halt light waves in a two-dimensional photonic crystal, as published in Nature Photonics.
- The breakthrough allows for precise control of light at the nanoscale, essential for developing high-performance nanophotonic chips.
- Unlike electrons that respond to magnetic fields, photons lack charge and require alternative methods for manipulation.
- Inspired by electron behavior in materials, researchers engineered materials to mimic a 'magnetic field-like' effect for photons.
- By deforming the photonic crystal, researchers could control light waves similarly to how a magnetic field influences electrons.
- The researchers achieved a revolutionary method to confine and halt light waves at the nanoscale within the crystal structure.
- The ability to control light waves on a chip offers potential for efficient optical devices, lasers, and quantum light sources.
- Collaboration with Delft University of Technology led to successful demonstration of halting light within the photonic crystal.
- Similar discoveries were made independently by a team at Pennsylvania State University, reinforcing the potential applications of this technology.
- Stopping light waves in photonic crystals opens new possibilities for nanophotonics and could impact fields like optical communication and quantum computing.
