Enantioselective optical trapping and characterization of all dielectric disorder-enabled chiral particles
Guilherme T. Moura, Tanja Schoger, Kainã G. Diniz +9
We trap submicroscopic silica spheres coated with randomly distributed titanium dioxide nanoparticles in optical tweezers with Laguerre-Gaussian modes and observe orbital dynamics…

Circular Dichroism without absorption in isolated chiral dielectric Mie particles
Rafael S. Dutra, Felipe A. Pinheiro, Diney S. Ether +3
We demonstrate that an effect phenomenologically analogous to circular dichroism can arise even for dielectric and isotropic chiral spherical particles. By analyzing the polarimetr…
