Abstract

It is known that metasurfaces – two-dimensional structures consisted of periodically spaced nanoresonators of various shapes – can be used for spatial filtering of light, particularly for image processing applications. In this work, spatial Fourier filtering based on semiconductor metasurfaces is proposed to implement complex analog operations on the optical signal. We design, create and test a metasurface composed of silicon nanodisks implementing the convolution of an arbitrary image with a reference one. An ultrafast tunable Fourier filtering based on the gallium arsenide metasurface under femtosecond optical pumping is also proposed. The results of this study can be used to create a compact and lightweight optical devices for image processing applications.
