Microfabrication method development

FABulous is investigating two complimentary approaches for high resolution, high speed, multi-photon 3D printing of 3D metasurfaces. The aim to identify the optimum method for manufacturing metasurfaces with different applications.

The first approach is based on massively parallelised lithographic printing which has been shown to enable writing of up to millions of voxels per exposure while  reducing 3D proximity effects.

The second approach uses a technique called holographic layer by layer 3D printing, which uses spatial temporal pulse shaping to further reduce or completely remove undesired out-of-plane polymerisation.

Example structures produced by the FABulous team using these techniques are shown on the left.

Integrated Metasurface Design and Process Modelling

Industrial scale manufacturing of products with integrated metasurfaces requires the development of methods and tools that connect system level design with metasurface design so that the resulting product can fully exploit the unique functions that the metasurface can provide.

FABulous is therefore developing approaches for multi-scale simulation of metasurface enabled products from nano-scale to meter-scale. Our current work is exploring the use of rapid simulation to co-optimize the metasurfaces with the optical elements of the target products. Ensuring  that the final products take maximum benefit from the integrated metasurface.

An example comparison of the results of our simulation work with experimental results is shown on the right.
