Arbitrary polarization control with reconfigurable metasurface systems
Abstract/Contents
- Abstract
- The fundamental motivation of this work is the lack of versatile polarization components. In particular, while there exist methods for creating fixed achromatic waveplates and for tuning the birefringence of single wavelength waveplates, there is no universal waveplate that both works over a broad wavelength range and can be reconfigured to a desired retardance. We will show how metasurfaces—ultra-thin nanophotonics devices—can be combined to create systems capable of achromatic reconfigurable birefringence using a novel dual-metasurface platform. These systems rely on symmetry breaking though micro-scale displacements to modify the polarization state of incident light. We analyze these systems both theoretically and characterize them experimentally. In addition, we generalize this method beyond the naturally occurring basis of linear polarization to entirely arbitrary polarization bases. These arbitrary elliptical waveplates provide versatility for on-demand polarization control. We further show how these reconfigurable systems can be cascaded to form systems that are capable of generating arbitrary polarization states from a given input polarization. This polarization state generation is shown to be achromatic and has the potential for ultra-fast tuning speeds.
