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)

We describe the realization of a phase-sensitive and ultrafast near-field microscope, optimized for
investigation of surface plasmon polariton propagation. The apparatus consists of a homebuilt
near-field microscope that is incorporated in Mach-Zehnder-type interferometer which enables
heterodyne detection. We show that this microscope is able to measure dynamical properties of both
photonic and plasmonic systems with phase sensitivity. © 2008 American Institute of Physics.
