Start date 1 October 2017
Duration 3.5 years
The project will result in design and assessment tools for semiconductor lasers aimed primarily at data communications. This will involve the development of a DFB laser model, incorporating the effects of the injected carriers, through many body interactions, on the electrical and optical performance and which produces expected performance data for both the final device but also for test structures fabricated on wafer. This facilitates a detailed understanding of how both the material and structure properties affect the laser performance as a function of operation temperature. And for feedback during the fabrication process to benefit manufacturing efficiency / yield. We expect the student to develop a leading understanding of the design of manufacturing tolerant optoelectronic components, to implement novel design ideas and to develop cutting edge skills in the modelling, fabrication and characterisation of semiconductor materials and devices. The postgraduate student will work closely with other researchers in Cardiff working on the ESPRC Manufacturing Hub in Compound Semiconductors and colleagues in Compound Semiconductor Technologies (https://www.cstglobal.uk/) and the Compound Semiconductor Centre (CSC) where the laser material will be grown. Candidates are expected to have a strong background and interest in Optics/Photonics and Semiconductor Physics.
