What to know about Nano-optics: New mechanism for channeling light waves discovered in natural hyperbolic materials

Researchers from the University of Stuttgart and the Istituto Italiano di Tecnologia have discovered a method to direct light waves using the intrinsic properties of the biaxial material molybdenum oxy-dichloride. This 'plasmon canalization' allows for directional light transport without the need for complex, nanofabricated waveguides, potentially simplifying the production of photonic chips and quantum technologies.
