Fully Funded PhD Studentship in Metamaterial/graphene active terahertz modulators and detectors


Project Description

The Department of Engineering at Lancaster University is pleased to announce the availability of a fully funded PhD studentship in Electronic Engineering, to commence in January 2019.

This project will involve the theoretical design, simulation, fabrication and testing of optoelectronic devices such as frequency modulators, polarization modulators and beam steering devices based on metamaterials and graphene, operating in the terahertz (THz) frequency range. The THz range (1-10 THz corresponds to vacuum wavelengths between 30-300µm) represents an exciting portion of the electromagnetic spectrum with unique applications in the field of communications, spectroscopy and imaging, where there is presently a lack of efficient optoelectronic devices. This research aims to overcome the present limitations by providing an innovative class of active devices by engineering the interplay between resonant metamaterials and active materials such as graphene. The project is based on the expertise and collaborations developed in recent years in the topical areas of integrated modulators and detectors [1-4]. Graphene samples and expertise will be provided by the established collaboration with University of Cambridge. The PhD candidate will develop expertise in device fabrication using standard clean room techniques, as well as proficiency in device characterisation using facilities available in the Engineering Department. The candidate will also have the opportunity to visit the Cavendish Laboratory at the University of Cambridge for the final device testing in a different experimental environment, e.g. with THz quantum cascade lasers.
