Research at DTU Fotonik
Our research is grouped in four sections:
We study the ultimate limit of core density and inter-core crosstalk properties in uncoupled multi-core fibers (MCFs), mode density of multimode fibers, silicon photonics grating couplers as fan-in fan-out (FI/FO) devices for MCFs.
Since the invention of the laser, the ability of controlling the properties of light and its interaction with matter has led to major breakthroughs in a wide area of applications, including telecommunication, biology and medicine. Our information society relies on narrow beams of light being transmitted around the globe using optical fibres the width of a human hair. Tiny beams of light can also be used to manipulate small particles, including individual cells, with huge potential in diagnostic and therapy.
However, the shape of the light beam itself has until now received very little attention. Being able to mould the spatial properties of light could have a huge impact on those applications. Higher capacities could be carried over optical fibres if beams with different spatial profiles could be transmitted together, thus resolving a foreseen shortage of bandwidth in the near future. New tools including additional degrees of freedom could be developed for enhanced interaction of light with matter, with huge potential impact in imaging, diagnostic and cell manipulation.
Interestingly some common technology platforms could be used for such distant applications as telecommunications and biology. It is these technologies we propose to explore and develop in this highly interdisciplinary project. In particular, we will study how advanced beam shaping techniques and new optical fibres specially developed to transmit these beams can be used for a wide range of applications.
This project proposes to demonstrate how an enhanced control of the field distribution of light can lead to breakthroughs in a wide range of applications, including high-capacity optical fibre communications and the emerging field of nano-biophotonics.
