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

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.
