Abstract

In this presentation, we will highlight our most recent work in the field of optical force spectroscopy. Using a Mie particle, trapped in the evanescent field, we are able to visualize the force field acting on the particle. The technique combines a lock-in algorithm and advanced Mie simulations to obtain force measurements with unprecedented accuracy. Finally, we highlight the rich dynamics that occurs when varying different parameters in the setup.
