Ongoing collaborations
 |
We are collaborating with Prof. Christian Koos group at Institute for Photonics and Quantumelectronics (IPQ) at Karlsruhe Institute of Technology on the investigation of possible telecom applications for integrated SiN frequency combs fabricated in our group. | 2012 – present |
 |
We are collaborating with Prof. John Bowers at UCSB within the framework of the DARPA DODOS program on the development of fully monolithically integrated optical frequency synthesizers. Other partners include K. Vahala (Caltech), S. Diddams (NIST), K. Srinivasan (NIST). The overarching aim is to make optical frequency synthesis compact and ubiquitous. | 2014 – present |
 |
We are collaborating with Prof. A. Nunnenkamp at University of Vienna on open theoretical questions in quantum optomechanics. He was formerly at Cambridge University where we collaborated within the framework of the Horizon 2020 FET Proactive program on Hybrid Optomechanical Technologies (HOT). | 2017 – present |
 |
We are collaboration with Prof. A. Ferrari‘s research group at the University of Cambridge Graphene Centre within the framework of the Graphene Flagship on functionalizing high Q optical microresonators with 2-D materials for optoelectronic devices. | 2017 – present |
|
We are collaborating with Dr. Paul Seidler from IBM Research Zurich GmbH within the framework of a project funded by the Swiss National Science Foundation on Quantum-coherent electro-optic microwave-optical conversion with GaP and BaTiO3 (QuantEOM). We are also part of the Academic Program IBM Quantum Network where we collaborate on the development of quantum communication interfaces to superconducting qubits based quantum computers. Within the SNF project Sinergia we collaborate on the development of heterogeneously integrated nonlinear photonics for quantum applications. | 2012 – present |
We also benefit from our cleanroom facility at the EPFL Center of MicroNanoTechnology (CMi).
Past collaborations
 |
Together with Prof. Rudolf Gross (director of Walther-Meißner-Institut & faculty of Technische Universität München) we worked on experiments in the field of electro-nanomechanics. We carried out measurements with superconducting coplanar waveguide microwave cavities with integrated nano-mechanical oscillators at a dilution refrigerator temperature (<100mK). | |
 |
We collaborated with Dr. Ronald Holtzwarth, CEO of Menlo Systems GmbH within the framework of the DARPA PULSE program on the development of a low phase noise microwave generation using optical frequency combs that can outperform state of the art crystalline quartz devices and be used in applications ranging from long baseline interferometry, radio communications to radar. | 2007 – 2020 |
 |
We collaborated with Microsoft on use of soliton microcombs in optical data centers. This collaboration is jointly with Dr. Hitesh Ballani, at Microsoft Research UK. |
2018 – 2020 |
 
|
We collaborated with the Russian Quantum Center and the Faculty of Physics, M.V. Lomonosov Moscow State University within the framework of the Swiss National Science Foundation Scientific & Technological Cooperation Program Switzerland-Russia (STCPSR) on exploring temporal solitons in optical microresonators for visible and Mid IR based optical frequency combs. |
2007 – 2020 |
|
We collaborated with Dr. T. Herr and Dr. S. Lecompte at CSEM within the framework of an ESA project to develop a compact low noise microwave source based on optical hyperparametric oscillations. |
2017 – 2021 |
