In existing control methods for optical tweezers, the trapping stiffness is usually assumed to be constant and known exactly. However, the stiffness varies according to the size of the trapped ...

Gentle manipulation of micrometer-sized dielectric objects with optical forces has found many applications in both life and physical sciences. To further extend optical trapping toward the true ...

Impact Statement: We theoretically demonstrate that planar rectangular dielectric waveguides can support in-plane transmission of optical vortex modes, carrying orbital angular momentum. As compared ...

In recent years, optical micromachines based on forces exerted by strongly focused beams of light have started to provide unprecedented access to nonintrusive measurement and manipulation of matter on ...

Metamaterials made of magnetic photonic crystals have been generated and tuned to a theoretically predicted transition point at which peculiar optical properties emerge. For example, when light is ...
