Abstract
Optical tweezers normally rely on the intensity gradient force to trap and manipulate microscopic objects in the transverse plane of a laser beam. The phase gradient of light provides a new degree of freedom to create transverse optical force on the trapping plane, which has been applied to control micro- and nanoparticles. Here we introduce holographic beam shaping methods to create complex light with structured intensity and phase, and demonstrate versatile optical nano-manipulation, such as optical trapping, sorting, and transporting of nanostructures by dynamically sculpting the phase profile of light.
