Optical Trapping on Waveguides

O.G. Hellesø [1],
[1] University of Tromsø, Tromsø, Norway

On the surface of an optical waveguide, there is an evanescent field. The evanescent field decays fast and this steep gradient can be used to pull nano- and microparticles down towards the waveguide surface. Radiation forces will propel the particle forward along the waveguide. Trapping ... Mehr lesen

Photoacoustic Modeling Using Amplitude Mode Expansion Method in a Multi-Scale T-cell Resonator
