About
COntrolling network RAndom Lasers on chip — CORAL is an H2020 Marie Skłodowska-Curie Innovative Training Networks project under Grant Agreement Number 859841. The principal investigators are Dr. Kirsten Emilie Moselund, in IBM Research GmbH, which is an industrial research laboratory located in Rüschlikon, Switzerland, and Dr. Riccardo Sapienza, in the Physics Department of Imperial College London. CORAL started in 2020, and will run through 2024.
Description
The photonics industry in Europe is in rapid growth, lasers in particular have played a central role in several technological developments for many decades, from communications to medicine. As photonic devices shrink in both physical size and power consumption, integrated photonic devices will increasingly penetrate into consumer products such as smartphones and photonic sensors, for various applications from motion detection to navigation of autonomous vehicles.
The European Industrial doctorate program CORAL will address the increasing need for educated professionals in this field, by the training of two young researchers in photonics technology and in particular in the relatively new field of network lasers, which is at the cross-roads between nanophotonics and neuromorphic applications.

Jakub Dranczewski is a PhD student as part of the Marie-Sklodowska-Curie Innovative Training Network project CORAL together with IBM Research Zurich. He has graduated with an MSci degree in Physics from Imperial College London, and has previous experience working in Physics labs across Imperial College and the Polish Academy of Sciences.
IBM Research Europe
Dr. K. E. Moselund manages the Materials MIND group at IBM-Research Europe, which focuses on research on future devices and nanoscale characterisation, in particular the monolithic integration of III-V materials for electronic and photonic devices. She has more than ten years of experience with working on novel electronic and photonic devices and concepts. She is an ERC grantee - PLASMIC on the development on plasmonically enhanced integrated light-sources. She has co-authored more than 75 scientific contributions.
Dr N. Vico Trivino is an engineer in the Quantum Technologies group at IBM-Research Europe. Prior to joining IBM, Dr. Vico Triviño was a post-doctoral researcher in the Microsystems Technology Laboratories of the Massachusetts Institute of Technology (MIT), where her research was funded by a personal career development grant from the Swiss National Science Foundation. Dr. Vico Triviño holds a PhD in Photonics from the École Polytechnique Fédérale de Lausanne (EPFL), Switzerland, and a Master's degree in Electronics Engineering as well as a B.S. degree in Physics from the University of Granada, Spain.
Imperial College London
Prof. R. Sapienza leads the Complex Nanophotonics group in Imperial College London. Dr. Riccardo Sapienza has performed fundamental studies on random lasing and light transport and emission in disordered photonic materials for over 15 years. He has published 50 articles in high impact journals with over 4000 citations. Currently, he is the recipient of three EPSRC Research Grants. He has initiated the Photonics Online Meetup (http://photonicsonlinemeetup.org) and the Complex Nanophotonics Science Camp (http://www.sciencecamp.eu).
Dr. D. Saxena is a Marie Skłodowska-Curie Individual Fellow in the Complex Nanophotonics Group in Imperial College London. His fellowship is focused on developing semiconductor network random lasers that can be electrically pumped. He has over six years of experience in designing and characterising III-V semiconductor nanolasers. He demonstrated the first GaAs nanowire laser operating at room temperature.
