Abstract
Nanophotonics, situated at the nexus of nanotechnology and photonics, explores the intricate interplay between light and matter on the nanoscale. This dissertation embarks on a journey through two pivotal realms within nanophotonics: metasurface-based vision systems and radiative cooling technology. In the contemporary landscape of nanophotonics, metasurfaces have emerged as versatile platforms, offering unprecedented functionalities in imaging and optical manipulation. This dissertation first delves into the realm of meta-optics, elucidating the design and characterization of metasurface-based structured light 3D imaging systems. A novel full-space diffracting metasurface is proposed, facilitating ultra- wide field-of-view depth imaging, thus revolutionizing applications in fields like depth sensors and 3D vision technology. The following chapters navigates through the realm of radiative cooling, an increasingly vital facet of sustainable energy management. Through meticulous numerical simulations and practical experimentation, this dissertation investigates the optimal design parameters for passive daytime radiative cooling devices. In addressing these cutting-edge advancements, this dissertation underscores the imperative of holistic device development, encompassing not only optical design but also computational tools, and system integration. By tackling the challenges of compatibility and economic feasibility head-on, this research strives to pave the way for the seamless integration of nanophotonic devices into diverse applications, thus heralding a new era of innovation and sustainability.
