PhD Research Project

Terahertz (THz) radiation has the potential to revolutionise applications in security, medicine and industry. It has however, been referred to as the “Final Frontier” of the electromagnetic spectrum because of the significant challenges associated with its generation and detection.

While THz technology has progressed dramatically in recent years, there is still a lack of robust THz sources which are compact, frequency-tunable and cost-effective. This project aims to develop new, compact, high-efficiency and frequency-tunable THz laser sources by making use of stimulated polariton scattering, a process which uses both second-order and third order non-linearities. The THz source architecture is similar to that of a solid-state Raman laser which itself is built upon cost-effective and proven diode-based pump sources and crystalline materials.

This project will involve exploring methods by which the overall THz output power, extraction efficiency and tuning range can be maximised through the use of different resonator designs, crystals and novel extraction methods which involve the use of photonic crystal structures. Latter stages of the project may also involve investigating the application of the generated THz emission to perform spectroscopy and imaging of concealed materials.

The project will be tailored to suit the interests and strengths of the successful applicant - the project is primarily an experimental one, however there will be also be scope for theoretical or numerical modelling studies.

Funding Notes:

This project will suit a motivated student interested in optical physics, non-linear optics and laser design.
