Optical components, including lenses, prisms, and waveplates, have been known and used for centuries. Their production often involves hand polishing, and the approach to its production hasn’t changed since. Metalens - flat nanostructured surface - is a novel platform that allows the production of various optical elements using a CMOS-compatible fabrication approach. The metalens can combine the functionalities of several optical components into a single device, providing multiplexing capabilities. It is lightweight and possesses a small form factor, making it suitable for AR/VR technologies, mobile phones, and space applications. In this talk, I will describe the principles behind the design and fabrication of metasurfaces. To demonstrate the power of this platform in designing optical components, I will show examples of metaoptical devices realized in the literature.
