Prof Oleg Mitrofanov’s paper on terahertz technology featured in Advanced Photonics Research

The research team developed and demonstrated a new type of non-linear THz metalens emitter - a flat, compact optical device that uses nanoscale materials and light to generate and simultaneously focus THz beams. This metalens, made from a material called indium arsenide (InAs), is photoexcited by short optical laser pulses, allowing it to create and shape THz pulses. This new technology combines two key functions in a single device: generating THz pulses and structuring them, and it can be used for various applications.

This innovation could have significant implications for future technologies, including THz imaging, spectroscopy, and wireless communication systems. The research shows how non-linear metasurfaces, like the one developed, can play a crucial role in advancing THz applications.
