Actively controlled metasurfaces for light manipulation and control
Abstract/Contents
- Abstract
- Metasurface optics have been developed for a wide variety of optical applications that compete with as well as go beyond the functionality of conventional optics. One upcoming challenge for future metasurfaces is the development of individually addressable optical properties that can be actively changed with controllable input stimuli. In this work, we will explore how electro-mechanics can be used to couple a mechanical degree of freedom to an optical response. We will see how the localized optical resonances within a silicon nanowire placed near a mirror can be leveraged as a building block for engineering an active metasurface. The tuning of the amplitude of scattered light will enable color-tunable active metasurfaces. By designing a structure with a modifiable phase gradient, both light steering and focusing can be controlled by an applied electrical signal. In addition to covering mechanically controlled active metasurfaces, we will also show that it is possible to use passive metasurfaces to gain real-time three dimensional information in a volume and that in certain cases, active metasurface optics are not the only solution to improve optical functionality.
