Optical vortex torque measured with optically trapped microbarbells
Weronika Lamperska, Jan Masajada, Sławomir Drobczyński +1
Optical vortex beams carry orbital angular momentum and thus exert torque on illuminated objects. A dielectric microtool - a microbarbell - is used in a two-laser optical tweezers…

Time-frequency Domain Analogues of Phase Space Sub-Planck Structures
Ludmila Praxmeyer, Piotr Wasylczyk, Czeslaw Radzewicz +1
We present experimental data of the frequency resolved optical gating (FROG) measurements of light pulses revealing interference features corresponding to sub-Planck structures in…
