The objective here is to combine all-dielectric and plasmonic metasurface concepts with chalcogenide phase-changematerials to provide fast, dynamic, and tunable control of the amplitude and phase of light. Such active control leads to a wide range of important technical applications, such as dynamic beam steering, holographic displays, reconfigurable and dynamic lensing, optical modulation and the focus of this work- optical analogue computing and multi/hyper-spectral sensing.

Analog optical computing has seen an increase in attention in recent years due to potential advantages it holds over its digital counterpart, including intrinsic parallelism, low-loss transmission and ultra-high bandwidth. Fast and energy efficient optical computing systems have been demonstrated, for example implementing neural networks and matrix-vector multiplication. In A-Meta we are developing metamaterial-based optical computing systems for a range of computational tasks, including image processing, matrix-vector multiplication, optical mode conversion and more.  Specifically - along with A-Meta collaborators at the City University of New York, the University of North Carolina at Charlotte and the University of Oxford - we have developed novel convolutional optical computing approaches using active phase-change metasurfaces that enable emerging applications in artificial intelligence-assisted imaging and vision devices with switchable multitasking.

Here we will address the lack of practical microwave and terahertz modulators by exploiting the change in conductivity of a semiconductor upon illumination with an optical light source by a novel approach to reduce charge carrier recombination. Fast, high-resolution, and efficient GHz-THz spatial light modulators will be transformative to a new generation of reconfigurable complex systems for imaging, communications, beam steering and more.

Having aligned the optical excitation array with a periodic metasurface, we are able to controllably excite small regions around each meta-atom, and probe its function to the metasurface response. The image shows the photoactive regions around individual meta-atoms in a dual frequency band metasurface: we see individual switching of meta-atoms in both the low (red) and high (green) frequency bands of the surface, as well as defective meta-atoms.

We will develop a new generation of dynamically tunable elastic-wave metamaterials from the micro- to the macroscopic to address (i) the creation of phononic test artefacts enabling in-situ monitoring of additive manufacturing (AM) processes, and (ii) the incorporation of advanced materials, using AM, to create tunable phononic materials and devices for applications such as signal processing.
