Silicon photonics is a rapidly growing industry, potentially reaching an annual value of over a billion dollars in the coming decade. In parallel, the complexity of photonic integrated circuits has increased by more than an order of magnitude. The optical response of silicon at wavelengths used for telecommunications, however, is relatively weak. Current optoelectronic technologies therefore rely on integrating other materials with the desired properties. In this context, graphene has emerged as an excellent candidate to realize silicon-compatible optoelectronic devices. Graphene is an atom-thick, two-dimensional material made from carbon. It is nearly 100 times stronger than steel, conducts heat and electricity efficiently, and has unusual optical properties. Recent experimental reports have already approached the predicted performance limits of graphene-based devices. It is not obvious how the device performance can be further enhanced while simultaneously reducing device size. Thus, new paradigms in graphene-based optoelectronic devices/sensors are required. This project will develop a new approach for realizing integrated optoelectronic devices. Nanofabrication will be used to integrate graphene into active devices and engineer the effective optical properties with nm scale resolution. These devices will be fully compatible with CMOS technology and promise dramatic reductions in device footprint and losses, while providing fast-speed with low energy consumption.
The PhD studentship is part of a NSF-US/Ireland R&D Partnership with research collaborations between the Queen’s University (Belfast, UK), Tyndall National Institute (Ireland) and the University of Utah (USA). International cooperation will provide exceptional opportunities for international student exchange and research collaboration as part of this project.
To undertake research into the design, fabrication, and characterization of optical sensors. In particular, to development of high-performance ultra-compact graphene based optical devices.
A minimum 2.1 honours degree or equivalent in Engineering (Electrical/Electronic Engineering, Material Science, Chemical Engineering, Chemistry, or Physics) or relevant degree is required.
