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 demonstrate a new technique that combines polarization sensitivity of the coherent anti-Stokes Raman scattering (CARS)response with heterodyne amplification for background-free detection of CARS signals. In this heterodyne interferometric polarization CARS (HIP-CARS), the major drawbacks of polarization and heterodyne CARS are rectified. Using a home-built picosecond optical parametric oscillator, we are able to address vibrational stretches between 600 and 1650 cm−1 and record continuous high-resolution Raman equivalent HIP-CARS spectra. © 2010 JohnWiley & Sons, Ltd.
