The revolution of materials science with structured light fields


  • Takashige Omatsu Chiba University, Japan


The optical vortex carries a ring-shaped spatial form, a handedness, and an orbital angular momentum (OAM) associated with its helical wavefront, and it has been revolutionizing a variety of research fields, such as optical tweezers and manipulations, optical/quantum communications, and optical data storages with the freedom of OAM. We have discovered that OAM of the optical vortex twists the irradiated materials to shape nano/micro-scale helical structures, manifesting a helical wavefront of the irradiated optical vortex. Such helical structures will pave the way towards advanced material sciences and technologies. In this presentation, we review the state of art advanced materials engineering based on optical vortex induced helical structures and beyond.
