Photonic Hook Could Enable Optical Manipulation of Nanoparticles
ST. PETERSBURG, Russia, March 20, 2018 — A curved photonic nanojet, called a photonic hook, was created using an asymmetric cuboid, formed by appending a triangular prism to one side of a cube. Using numerical methods, scientists showed that the trajectory of a probe nanoparticle in the shadow side of the cuboid was curved. When a glass obstacle was added to the system, the trajectory shifted toward another path, losing some of its curvature in the long-range. When a gold obstacle was added, the jet was reduced in size, and the
