THz imaging and microscopy, a multiplexed near-field TeraHertz microscope
None of the THz imaging techniques developed to date, permits high spatial resolution spectroscopic imaging at fast acquisition rates. In the classical THz sub-wavelength imaging with a single aperture, the image is composed by mechanically scanning the sample against a single sub-wavelength …

Flexible and substrate-free optoelectronic devices based on III-V semiconductor nanowires
… These thin films are used to fabricate a THz modulator and a solar cell. Single and multi-layer THz modulators are fabricated from nanowire-Parylene C thin films laminated together. 1,2,4,8, and 14-layer modulators are compared, with the 14-layer modulator displaying the best performance. …

Laterally confined THz sources and graphene based THz optics
… in the electromagnetic spectrum, the Terahertz (THz) gap, provides an exciting opportunity for future wireless communications as this band has been under utilised. This doctoral work takes a two-pronged approach into closing the THz gap with low-dimensional materials. The first attempt addresses …
