Optical Sciences

Biomolecules and nanostructures

The Optical Sciences group studies the interaction of light and matter at the nanoscale. We do this by exploring ways to shape light and its environment. It's what we call active and passive control. Our current focus is on the interaction of light with biomolecules and nanostructures. We are part of Twente University's Department of Science and Technology and member of the MESA+ institute.
We participate in the EU-COST actions MP1102: Coherent Raman microscopy (MicroCor) and CM1202: Supramolecular photocatalytic water splitting (PERSPECT-H2O)

ERC Consolidator Grant for Sonia Garcia Blanco

  Sonia Garcia Blanco had a successful grant application for the project RENOS (Rare-earth doped novel on-chip sources).
With the Consolidator Grant, the European Research Council (ERC) facilitates excellent researchers who have proven they are able to lead their own research group.
The ultimate goal of RENOS is the development of compact, low cost, power efficient, tunable lasers and frequency combs working at frequency ranges not easily achieved with current technology. A successful development of this technology will pave the road to great scientific advancements as well as a new generation of compact on-chip solid-state laser sources that will open new horizons in optical sensing, spectroscopy, metrology and telecommunications.
