In our ERC Consolidator Grant, SmartGraphene, we have been developing graphene-based devices to control terahertz radiation. We discovered that graphene devices can control both phase (~2pi) and intensity (>90%) of THz radiation very efficiently over a broad spectrum. The TeraChip PoC project is aiming to develop a technology for very-large-scale integration of these graphene-based THz modulators (>megapixel elements) on a single chip and demonstrate a THz imaging system using the high-density modulator array and a sensitive single detector. This approach will enable low-cost THz imaging which will unlock the full potential of THz waves for non-invasive imaging applications. The project will develop a strong business case for the commercialisation of the developed technology for the agricultural testing market. The expected outcome of the project is to bring our discovery to a development stage TRL4-5 with a strong business case, including technology demonstration
