Summary on Grant Application Form |
For centuries diamond has been highly sought after for manufacture into gem stones; the demand stems from its exemplary physical properties. Such remarkable characteristics also render diamond a promising host medium for many advanced technology applications. With recent breakthroughs in the manufacture of synthetic diamond substrates, the adoption of diamond into widespread device application is becoming ever more tangible. However, there is an urgent need for a scalable processing framework that can turn this hard, inert material into functional devices. In the course of this fellowship, I will develop a diverse toolkit based around laser fabrication which can fill this void. Through the use of short pulsed lasers and advanced optical techniques, accurate fabrication in three dimensions beneath the surface of diamond becomes possible.
Dependent on the laser power and how it is focused into the diamond, different processing regimes are possible. Electrically conductive wires may be printed in 3D running through the diamond, as can optical wires for routing light through the diamond. By reducing the laser power, it is possible to introduce just a single defect in the diamond lattice which can then be used as an information bit for quantum processing. Devices manufactured will include detectors of high energy radiation for use at CERN, 3D arrays of defects for quantum enhanced sensing and 3D photonic structures for manipulation of light. This will deliver a route to commercial diamond technology as well as a set of optical fabrication protocols that are transferable across wide technological areas.
The bulk of the work will be carried out at the Department of Engineering Science at the University of Oxford. There will be close collaboration though with partners at the Universities of Manchester, Warwick and Strathclyde, harnessing their unique capabilities to develop a complete photonics system for the creation of advanced technology devices in diamond.
