Biomolecules and nanostructures
The Optical Sciences group studies the interaction of light and matter. Our current focus is on detection and sensing/imaging with an emphasis on the development of integrated photonics. We are part of Twente University's Department of Science and Technology and member of the MESA+ institute.

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.
