- 요약An enormous amount of information, at every moment, falls into our visual system that are capable of sensing the brightness and color of light, which might answer why light has been intriguing us for such a long time. In fact, light carries information on its multiple degrees of freedom, not only the intensity and wavelength, but also the phase, polarization, and wavevector. This has laid the foundation for a variety of optical characterization and imaging methods to study materials, structures, or optical scenes that light interacts with. To implement and benefit from such methods, it is essential to achieve precise control over light waves based on these intrinsic properties of light.This has been typically obtained by using conventional optics such as lenses, filters, mirrors, polarizers, and waveplates. Such conventional optical components have played a pivotal role in optical and optoelectronic devices by delivering optical functions that are needed for their operation. To accommodate the demand for high optical performance, a set of conventional optical elements are often combined in an optical system with precise alignment. This strategy has been widely employed to build a variety of high-performance modern optical devices and instruments. For instance, digital cameras and microscopes rely on compound lenses to capture high-quality images with reduced aberrations. However, bulky conventional optical elements can offer limited optical functions that are determined by their shapes. As a result, optical devices with conventional optics inevitably involve a large form factor due to not only bulky optical elements but also the spacing between these elements.With the recent advents of various interdisciplinary technologies, novel optical and optoelectronic applications have emerged which impose new requirements that are hardly satisfied with conventional optics. To be specific, compact and light-weight optoelectronic devices are needed for their incorporation into a range of applications such as wearables, drones, and autonomous vehicles. Also, advanced optical functionalities are desired to facilitate emerging smart technologies in a range of fields including extended realities and computational imaging. Despite considerable efforts, it still remains elusive to completely fulfill these new technological demands with conventional optics, primarily due to their way of controlling light based on the shapes. Thus, these challenges urge for the creation of a new type of optical component that achieves control over light waves in a way beyond conventional optics.Recently, it has been recognized that light-matter interactions at the nanoscale can be harnessed to manipulate light waves in a controlled fashion, underlying the formation of so-called flat optical elements. This new type of optical element is typically composed of high-index dielectric nanostructures on a transparent substrate. Optical resonances in these nanostructures can give rise to strong light scattering that is naturally sensitive to a specific set of the physical properties of light waves. Moreover, their resonance properties can be readily tuned by the geometrical parameters of the nanostructures in a systematic manner. Through careful nanostructure design, a number of flat optical elements have been successfully created to replace their conventional counterparts by realizing similar optical functions in a compact fashion. As their optical functions are decoupled from their shapes, flat optical elements can be further engineered to enable novel optical functions that are unattainable by conventional optics.
