QUDOS 4th plenary meeting (internal)

Around 30 researchers from the four universities of QUDOS consortium (namely the University of Cambridge, Cardiff University, University of Southampton and UCL) gathered at Cambridge for the fourth plenary meeting of the QUDOS Programme Grant on 12 March 2024. This plenary meeting was a consortium members-only meeting for detailed technical discussion of the project developments. 

Alwyn Seeds of UCL, Principal Investigator of QUDOS, started the meeting by outlining the latest progress of the programme.  Researchers from the four universities then gave talks on the developments of their specific projects.

Huiwen Deng and Hui Jia of UCL described recent advances in InAs/GaAs quantum dot growth on GaAs and Si substrates, and Ge and Si buffer growth on Si substrates for quantum dot lasers. 

Frederic Gardes and Ilias Skandalos of the University of Southampton talked about the progress of the integration platform and the integration of quantum-controlled Stark effect optical modulators. 

Ben Jakobs, Pawan Mishra and Dun Qiao of Cardiff University talked about universally useable gain/absorption model for quantum dot materials, intermixing InGaAs quantum dot material, and multi-phase shift grating comb reflectors. 

Finally, Qixiang Cheng of the University of Cambridge and Christina Vivian of UCL talked about QUDOS demonstrations on switching, sensing and computing, as well as monolithically integrated III/V-on-Si microwave photonic transmitters. 

Researchers from the four universities also took the opportunity to highlight their research work through presentations and poster displays. 

There were lively and intense discussions among researchers throughout the meeting. The next full plenary meeting (consortium members plus External Advisory Board members) will be in summer 2024.

Researchers continued their exchange and discussions during the coffee and lunch breaks. 

Filled in inspirations and challenging ideas, the meeting provided an excellent opportunity for researchers to discuss and exchange on the specifies of their research work.
