Research

Our group focuses on research areas where Nanophotonics has a big impact, both fundamentally and technologically.

Silicon Photonics - Presentation about one of the very few areas in physics ever to be adopted in industry within less than 10 years of its conception.

Our main topics of research include:

In Optomechanics we showed that two nanophotonic cavities placed far away from each other can synchronize: not only their optical properties but also their their mechanical properties can be drastically changed. This enables completely new communication schemes where one device can be controlled by another (that could be miles away).

In Silicon Photonics we showed that enormous bandwidth can be transferred in waveguides using new, ultrahigh speed nanophotonic modulators with low power. This has tremendous applications in the world of data communications where ultrahigh bandwidth data could be moved on-chip with low power pumping enabling, for example, future supercomputers on-chip.

All of the different research areas are strongly interrelated. For example, in the New Photonic Materials and Fabrication area, our demonstration of gray scale lithography enabled the demonstration of new structures in the Optomechanics area. In the Nonlinear Photonics area our demonstration of comb generation enabled a new on-chip light source in the Silicon Photonics area. Further, our research interests are constantly evolving to keep up with important trends, and so we always look to extend our expertise into new areas such as imaging of the brain and optical non-reciprocity.
