Metasurfaces for future sensing, imaging, and display technologies

Metamaterials are a new, emerging class of high-performance materials that derive their unique, physical properties from the way they are structured. In this presentation, I will focus on the creation of 2-dimensional metamaterials (i.e. metasurfaces) by nanopatterning glass, semiconductor and metal films. I will argue that these metasurfaces are ideal building blocks for the next generation of optical elements and optoelectronic devices. I will highlight how metasurface functionalities can start to impact a variety of optical sensing, imaging and display technologies. For example, I will show how one can create transparent optical sensors on glass substrates that can extract valuable information from an optical scene. I will also discuss the use of integrated metasurfaces for new imaging modalities. The proposed optical elements can be fabricated by scalable fabrication technologies, opening the door to many commercial applications.
