Mesoscale Photonic Method Increases Range of Optical Tweezers
TOMSK, Russia, Aug. 27, 2020 — A team from Tomsk Polytechnic University (TPU), working with scientists from the V.E. Zuev Institute of Atmospheric Optics of the Siberian Branch of the Russian Academy of Sciences, has increased the operation range and stability of optical tweezers. In the team’s method, light, interacting with a microparticle, is focused in the form of a photon jet in the direction opposite the radiation incidence. The photon jet functions as a trap.
