Research highlights include the:
- Demonstration of world record THz QCL powers, and the first use of photonic crystal structures, graded photonic heterostructures, and ‘spoof’ surface plasmons to engineer emission profiles.
- First demonstration of a THz pulse amplifier, and active mode-locking of a THz QCL, leading to the first measurement of sampling coherence in a QCL.
- Investigation of universal conductivity scaling in the high frequency quantum Hall regime, and the first picosecond probing of THz plasmons in coupled two-dimensional semiconductor resonators.
- First comparison of quantum mechanical and classical simulations of THz spectra, focusing on explosives, and the first spectroscopy of functional single crystal proteins under physiological conditions.
- First demonstration of new THz QCL imaging/spectroscopy methodologies, including self-mixing imaging, and the first waveguide-integrated THz QCL technology for in-orbit satellite demonstration of Earth observation.
