Integrated microwave photonics
|Photonics and radio signals join forces for high-speed mobile data communication, like in 5G communications. At the same time, the applications of ‘integrated microwave photonics’ go way beyond telecom. This progress often comes from directions you would not expect in the first place. In a review paper in Nature Photonics), David Marpaung gives together with experts Jianping Yao of the University of Ottawa and Jose Campany of the University of Valencia a vision on the next phase of photonic chips, for example in brain-inspired, ‘neuromorphic’ optical computing.

World's most narrowband diode laser on a chip
|Researchers of the Laser Physics and Nonlinear Optics group developed, in collaboration with researchers of the Lionix Company, the world’s most narrowband diode laser on a chip exhibiting a quantum limited spectral bandwidth of less than 300 Hz. This laser concept represents a breakthrough in the fast-growing field of photonics, and will bring applications such as 5G internet and accurate GPS closer (see also UT Press release).|
VIDI Grant for David Marpaung
David Marpaung (Nanophotonics), currently at the University of Sydney (http://sydney.edu.au/science/people/david.marpaung.php), has received a prestigious grant of the Netherlands Science Organisation (NWO, VIDI). His research is to be hosted in the Laser Physics and Nonlinear Optics group (LPNO) and the Applied Nanophotonic research cluster of the UT (ANP). His activities are supported by various Dutch companies that are working in the field of integrated photonics, for instance Lionix International, Smart Photonics BV and Phoenix BV.
Dr. Marpaung will investigate new technologies for integrated photonic systems, for processing information through interactions between light and 'hypersound', to realize, e.g., on-chip Brillouin processors for future wireless and optical networks.
