MACRO-SCALE AND LONG-RANGE OPTICAL ACTUATION WITH NANOPHOTONIC MATERIALS
Abstract
With the ability to coherently propagate over long distances with minimal loss, light can be a powerful tool for actuating objects without physical contact. Current approaches in optical manipulation are predominantly used for short-range control of very small particles that are typically nano-micro in size. The key to future advances lies in the ability to control optical forces in lightweight and large area structures. Here, we propose to overcome the challenges of conventional optomechanics by developing materials with precisely engineered nanostructure to scatter light for the control of radiation pressure forces. We will demonstrate the actuation of ultrathin, lightweight nanophotonic structures and develop insights into material synthesis for integrated multifunctional photonic capabilities in a subwavelength-thick form. Overall, the proposed project will advance the fundamental understanding of optomechanical interactions between high-power beams and ultralight optical systems, using the full arsenal of nanophotonic tools for the control of optical forces. Such control is key for developing new systems for long-range actuation, including for high-speed propulsion and metamaterial spacecraft without the need to carry onboard fuel.
