Integrated 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
A Poormans Superlens for Visible Light
We try to realize and test the first superlens for visible light. Its predicted imaging properties will be addressed with a combination of single molecule detection and near-field optics. The object that is to be imaged is a subwavelength aperture. Single molecules at the other side of the film will report on the local fields built-up by the lens. Their fluorescence intensity will reveal not only the magnitude of the electric field but also its direction. Variation of the relative position of object and detector (single molecule) will expose the imaging properties of the poormans superlens.
