PhD Studentship: THz Photomixer Arrays Enabled by 3D-printed phase-change lenses

Join the School of Physics and Astronomy at the University of Birmingham for groundbreaking PhD research that aims to improve Terahertz (THz) technology!

THz is a rapidly expanding field across a myriad of disciplines such as physics, engineering, chemistry and biology. THz radiation demonstrates unique properties for high-speed communications, medical diagnosis, security applications (chemical fingerprinting and standoff screening) and industrial control processes.

This PhD will champion the development of THz photomixer array sources whose functionality is enhanced by two-photon polymerisation direct laser written metalenses utilising phase-change materials and designed by multi-physics topological optimisation. This project will overcome current limitations of Si-lens integrated THz photomixers (i.e., output powers under few tens of μW in the range 0.3 to 1 THz, modest performance repeatability due to aligning manufacturing precision, and frequency-dependent radiation/receiving patterns with beam efficiency under 95%) resorting to photomixer arrays (up to 4 × 4) and 3D printed metalenses that can be fine-tuned after fabrication.
We expect the PhD candidate to develop the expertise required to lead an experimental research project, to train students, to interact with colleagues with different backgrounds (physics and engineering) and from different disciplines (i.e., electromagnetism, microwave engineering, material science, optics).

The School of Physics and Astronomy is an Institute of Physics Juno Champion since 2014 and holder of the Athena SWAN Silver Award. Both initiatives recognise the School’s commitment to promote diversity and equality, and to encourage better practice for all members of the community, whilst also working towards developing an equitable working culture in which all students and staff can achieve their full potential. We welcome applications from all qualified applicants and encourage applications from traditionally under-represented groups in physics and astronomy including, but not limited to, women and Black, Asian and Minority Ethnic.

The research programme will take place in the interdisciplinary environment of the Metamaterials and Nanophotonics group https://www.birmingham.ac.uk/research/activity/physics/quantum/metamaterials-nanophotonics, which will substantially favour collaboration opportunities within University of Birmingham and afield.

You can apply by clicking the 'Apply' button above (physics programme) clearly stating the title of the project and the name of the supervisor (Dr. Miguel Navarro-Cía)

Funding notes:

Applications are sought from highly motivated students graduating with first degree (2:1 or higher) in physics or engineering (and preferably a MSci/MEng degree). Funding is awarded by the School on a competitive basis, depending on the strength of the applicant. The funding will cover tuition fees and provide a stipend for 3.5 years.
