The advent of 5G telecommunication technology and has put strong foundations and demand for the development of the next generation of wireless communications, namely 6G. The 6G telecommunication technology is based on wave frequencies in the Terahertz frequency band, i.e. frequencies that are larger than 100GHz. Research and technology development at this frequency range is still at its infancy and there is still a long way to go until 6G telecommunications is mature enough to be deployed at a large scale.
One of the greatest challenges of this future technology is the transmission and distribution of very high frequencies (>100GHz) within a semiconductor device. Traditionally, for low frequencies (~1GHz), this is achieved through standard microwave waveguides, however at very high frequencies these waveguides are inefficient and result into high losses.
In this PhD project we will investigate novel transmission waveguides that achieve low loss propagation and distribution of very high frequency waves through topologically protected waveguide states. The topological nature of these waveguides means that waves can propagate on a device for long distances (several wavelengths) without any significant losses and protected from any material defects.
The PhD candidate will work on aspects of high frequency waveguides (THz) using topological nanophotonics. The PhD candidate will be involved in advanced nanofabrication in our state-of-the-art James Watt Nanofabrication Centre (JWNC), perform electromagnetic simulations of the devices and experimentally characterize the novel topological waveguides.
The project will require both individual and group work in collaborative environments and the successful candidate should be capable of working in both environments. Experience with computer programming (C or C++ or Python or Matlab etc), simulations (Comsol or Lumerical or HFSS) or data acquisition and analysis is not essential but it is advantageous.
