Nonlinear Ghost Imaging for Enhanced Terahertz Waveform Control in Scattering Media

Nonlinear Ghost Imaging in the terahertz regime offers a novel approach to spatial-temporal sampling, achieving resolution beyond the diffraction limit. In this work, we present an experimental study demonstrating how Nonlinear Ghost Imaging can be leveraged to achieve precise field-level waveform control through complex propagation in scattering media. This method enables agile terahertz waveform synthesis by exploiting near-field coupling between a distributed terahertz source and the scattering medium, paving the way for advanced manipulation of terahertz radiation in structured environments.

Short Bio

Vittorio completed his PhD in 2022 at the Emergent Photonics (EPic) Laboratory at the University of Sussex, with a thesis titled “Spatiotemporal Control of Terahertz Waves in Random Media via Nonlinear Ghost Imaging.” His PhD, funded by the ERC Consolidator Grant “TIMING” (PI: Prof. Marco Peccianti), initially focused on developing the Nonlinear Ghost Imaging methodology. He then extended his research to terahertz field propagation in random scattering media, contributing to the continuation of the TIMING project.Beyond this, Vittorio explored ultrafast nonlinear interactions for terahertz generation and field manipulation in complex photonic systems. In 2020, he contributed to the development of THink—a random terahertz-emitting ink—as part of the ERC Proof-of-Concept project THink (PI: Prof. Marco Peccianti). He is also the inventor of the project’s core patent, aimed at identifying the best route to commercialization. In September 2022, Vittorio joined Loughborough University’s Emergent Photonics Research Centre as a Research Fellow in Photonics. In 2024, he was awarded one of ten Vice-Chancellor Independent Research Fellowships at Loughborough University and also became a C-DICE Fellow.
