PROJECT SUMMARY Controlling light requires the engineering of materials, geometrical, and topological degrees of freedom to enable seemingly impossible optical effects and specially to enable novel devices and systems that are compact and power efficient. During the last decades, this control has been enabled and enhanced by advanced structures such as photonic crystals, metamaterials, and metasurfaces. The recent discovery of topological degrees of freedom brings an unprecedented new tool in the control of light. While significant progress has been made on bandgap engineering using topological concepts, it has not been extensively used to control light at surfaces or metasurfaces. Thin structures such as metasurfaces are promising as they address the small weight requirement for many Army systems. This proposal will investigate topological degrees of freedom for controlling light at metasurfaces. The project will investigate the new physics of such wave controls structures as well as novel properties enabled by topology. These devices will find applications in many Army systems where compact and efficient structures are required. The research will 1) investigate the physics of topological metasurfaces, 2) fabricate and characterize topological metasurfaces and 3) realize novel devices based on topological metasurfaces. The project objectives will be accomplished by combining expertise in the design, the fabrication, and the characterization of nanophotonic devices. The project bridges the fields of topology, electromagnetism, and photonics, as well as devices and requires theory/simulation, nanofabrication, and characterization.
